INSULATORS AND INSULATION TUBES
Insulators and insulation tubes made of F99.7 and F99.7 hf
can be fitted with ribs and glazed on the outside. The
rib structure increases the creepage distance, leading
to higher dielectric strength when used in atmosphericapplications. The glaze facilitates handling and cleaningof the component.

Depending on the construction, our insulation tubes are
suitable for cryogenic applications using liquid helium or
liquid nitrogen at temperatures ranging from -271°C to
450°C.
Operating temperature: 580°C to 675°C (high temperature).
As standard, the insulation tubes are tested for vacuum
tightness and can be fitted with different flange types
such as CF, KF or COF.

TESTINGPOSITIONING

With the trend towards the development and manufactureof even smaller chips, there is no way around KYOCERA
Fineceramics Solutions GmbH products. After all, computercomponents must be measured and checked in the µm
range before initial operation. Material properties such as
high dimensional stability at high temperatures turn ourceramic components into high-precision components.

High-performance ceramics are used in handling andpositioning systems for wafer manufacturing because
they are highly resistant to temperature, have excellent
electrical properties and are dimensionally stable.

PARTICLE ACCELERATOR
Oxide ceramics are the ideal material for demanding
applications in physical fundamental research, particle
physics and materials research. Its material properties
meet the very highest demands even under extreme
conditions. Vacuum chambers made of high-performance
ceramics are used in accelerator units. They are used in fastpulsed bending magnets to contribute to the injection andextraction of particles.
The requirements imposed on components made of oxide
ceramics during operation are very demanding. Sufficientmechanical strength and high durability guarantee safe
operation.

Components made of ceramic-to-metal joints are outstanding due to excellent properties such as maximum
electric insulation, absolute tightness even when exposed
to extreme pressure and vacuum conditions, exceptional
corrosion and temperature resistance at temperatures
exceeding 350 °C. Unlike metallic parts, ceramic components
prevent the shielding of the rapidly changing external
magnetic fields. Ceramics do not heat up when exposed to
eddy currents. The additional coating on the inner surfacesof the ceramic chambers, e.g. Ti or TiN, ensures that image
currents are reliably discharged and minimises secondary
electron emission.

CONSTRUCTION AND
MATERIAL SELECTION
Construction affects approximately 70% of manufacturingcosts. As a result, the construction has the task of providing
the customer with a product that meets his or her
requirements while at the same time ensuring competitive
product manufacturing prices.
This means in particular:a) 	Implementation of required property features using
simple solutions and standardised primary productsb)Construction suited to ceramicsc)
Construction suited to production
The choice of ceramic and metal materials suitable forjoining requires comprehensive knowledge of application
conditions. Table 1 gives an overview of the main requirements imposed on the three constituents of joining, i.e.
ceramic, joining area and metal.
Joint constructions are designed in accordance withgeometric requirements of the user and the thermalsuitability of the selected materials (see table 3 (p. 17)).

Table 2 shows some basic types of joint constructions which
are frequently used for feedthroughs and insulating parts.
The ceramic-to-metal joint is designed in such a way thatthe metal part, once brazed, exerts compressive stress on
the ceramic part. Construction type 1 comes close to thespecified target. When it comes to external brazing, metalalloys (Ni42, NiCo 2918) or metals with a coefficient ofthermal expansion (CTE) higher than that of ceramics are
preferred. These alloys are also suited for internal brazing;
however, the CTE of other metals should be lower thanthat of ceramics. Metals such as copper are an exception,
as these materials exhibit a high ductility and are used forinternal brazing despite of their high CTE. Adapted alloys or
ductile metals with wall thicknesses up to 1 mm are used
for external brazing. Larger diameters require the use of
moveable shaped parts. If these are magnetisable, e.g. a
Ni42 flange of type 1c is subsequently welded to a stainlesssteel flange (see Figure 11 (p. 22)).

If circumference or internal brazing is required on bothends of a tube, a groove is cut into the ceramic (type 1b).
The advantage of this construction is that it keeps brazing
equipment to a minimum and allows the individual brazed
parts to be mounted easily.

Feedthroughs are exposed to high mechanical stressand require that only compressive stresses occur inside
the ceramic. If this construction principle is taken into
consideration, highly resistant feedthroughs can be
manufactured.

The use of construction type 1 is often limited to brazed
diameters smaller than 50 mm when using non adapted
metals, because the difference in the CTE of ceramics andmetal at brazing temperature is too high. In such cases,
construction type 2 is often used.
The same applies when brazing larger metal parts made ofaustenitic steel via a ductile intermediate copper layer, as
this type of construction allows great mobility of the metalparts on the front edge of the ceramic part.
Compact constructions of type 3 are manufactured using
adapted metal alloys or ductile metals. The mechanicalsafety of such a joint is increased by using a ceramiccompensation ring of type 3b.

BRAZING TECHNOLOGYWith the exception of some products, usability requires
material-bonded and highly vacuum-tight joining of
ceramic parts with each other and with metal parts.
Various joining techniques can be used to achieve this.

GLASS BRAZINGGlass brazing is appropriate for gas-tight joining of ceramiccomponents. This joining technique is characterised bya very good general chemical resistance and operating
temperatures up to approx. 1,100 °C. These joints achievestrength values up to 100 MPa at room temperature (inaccordance with DVS German Welding Society, Guideline3101).

A coefficient of thermal expansion adjusted to the ceramic
and the glass braze is decisive for the quality of the glassbraze joint. There is great freedom of design with regard
to geometries, however, a suitable braze reservoir and an
adequate brazing gap in the construction must be guaranteed. This joining technique is based mainly on the use ofglass brazes with a thermal expansion matched to that ofceramics as glass shows no metallic ductile properties.

Table 3: Brazing materials and brazing temperatures

Metallisation allows for brazing at temperatures above
1,000 °C under protective gas atmosphere and/or in
the vacuum. A silver-copper eutectic alloy is used as astandard brazing material. Brazing materials with increased
melting properties are applied when higher requirements
are imposed on the operating temperature, corrosive
properties and use of metals that are hardly wetted by
the silver-copper eutectic alloy. Table 3 gives an overview
of available brazing alloys. Our metallised ceramics areavailable with galvanic coating such as Au, Ni or Cu toallow for the use of soft solders at low temperatures.

Relative length change (mm/m)

Components made of high-performance ceramics are
generally metallised using the molybdenum-manganeseprocedure (MoMn procedure) and subsequent nickelplating (see fig. 5a). The starting point for this process
is a compound of molybdenum and manganese. The
compound is applied to the ceramic surface to produce a
firmly bonded metallised coating through a firing process.
As the majority of commercial vacuum hard solders do
not wet the metallised surface, it is nickel-plated using agalvanic or autocatalytic method. The component can bebrazed on this base metallised coating.

BRAZING TECHNOLOGY

Ceramic components prepared using this metallisation
process can be hard-soldered with thermally adapted metalcomponents such as NiFe 42 (e.g. VACODIL), NiFeCo (e.g.
VACON 10/70), Ti, Mo, CU, etc. Figure 3 shows the coefficients of thermal expansion of different metals comparedto that of F99.7.

Figure 4 shows the cross-section of a joining area of a
F99.7/AgCu28/1.3917 compound. Tensile tests show that
this material combination results in strength values exceeding 100 MPa (in accordance with DVS German Welding
Society, Guideline 3101). If the construction is appropriate,
these strengths can also be achieved using active brazing.

ACTIVE BRAZING
Active brazing (see fig. 5b) is based on the use of brazing
materials with a low oxygen-reactive metal content suchas Ti, Zr, or Hf. They contribute to wetting of Al2O3 thus
eliminating the need for prior metallisation. The strength
values of directly brazed Al2O3 ceramics/Ni42 joints achieve
values similar to those of brazed and metallised joints.
Figure 6 shows a further example of a joining area of a ZrO2
ceramic and steel joint brazed with AgCu26, 5Ti3.

Al2O3ceramic

Although active brazing is attractive from a technical andeconomical point of view, its use with feedthroughs isrestricted because the braze does not flow into the brazing
gap but remains in the braze deposit. However, theserestrictions can be avoided when the constructions takethis particularity into consideration.

OPERATING VOLTAGE AND
CURRENT-CARRYING CAPACITY

Specification of flashover voltage values refers to the
distance between two voltage-carrying electrodes undernormal conditions (1,013 mbar, 50% relative humidity)
where no flashover occurs. Their values increase 3-4 times
in a vacuum of approximately 10-6 mbar. High pressuresof suitable dry gases or the use of insulating oils can also
contribute to such an increase. The values also dependon the electrode geometry. If the ceramic body covers theelectrodes, the flashover voltage depends only on creepage
distance; the operating voltage can be removed from thediagram (see fig. 7).

The current-carrying capacity of the feedthroughs depends
mainly on the type of conductor used. The specificationsin the diagram (see fig. 8) are intended as general values.
In specific cases, heat dissipation of the insulator must be
taken into consideration.

ELECTRICAL RESISTANCE AND BENDING
AND COMPRESSIVE STRENGTH

When comparing the specific electrical resistance ofdifferent insulating ceramics as a function of temperature,highly pure ceramics show very good insulating properties
even at higher temperatures (see fig. 9). While this highelectrical resistance (approximately 1014 Ω cm at room
temperature for F99.7) results to a large extent from thelack of alkali, porcelain and other ceramic insulating bodies
contain electric charges which are easy to move.
Our ceramic-to-metal assemblies are made of F99.7 material.
To avoid the effects of contamination on the surface ofoxide ceramics, our ceramic-to-metal assemblies can begiven a glaze with high melting points.

The compressive strength of ceramics is higher than thatof metals at any temperature range. Although lower atroom temperature, their bending strength exceeds thatof metals above 700 °C. The reason for this behaviour isthat the elasticity and fracture limits of ceramic materials
coincide and occurring stress cannot be reduced by plastic
flow. Unlike metals, our ceramics show no significant loss
in strength at higher temperatures (see fig. 10).

CONSTRUCTION CHARACTERISTICSTEMPERATURE RESISTANCE
Hard-soldered metal-to-ceramic joints are particularly
suitable for use at higher temperatures up to 600 °C in
the vacuum or protective gas. Depending on size anddesign, the thermal shock resistance of ceramic-to-metal
assemblies is approx. 180 °C. A heating up and cooling
down rate of 5 °C/min. is a generally accepted reference
value.

CONSTRUCTION NOTES
While installing ceramic-to-metal assemblies made ofhigh-performance ceramics, it is important to keep thermal
stresses occurring during welding or brazing away fromthe ceramic-to-metal mating surfaces. This can be taken
into consideration by using suitable design, flanges orappliances for heat dissipation.

Ceramic-to-metal assemblies are generally tested withmass spectrometer leak testing using helium as testgas with a sensitivity of approx. 10-9 mbar l/sec. External
partners are available for compressive strength tests ofceramic-to-metal assemblies. Feedthroughs are exposed tohigh mechanical stress and require that only compressive
stresses occur inside the ceramic. Taking into consideration
this construction principle allows for manufacturing ofhighly resistant feedthroughs.
Unless otherwise indicated, general dimensional tolerancesin accordance with DIN 2768 medium (metal) and DIN
40680 medium (ceramics) apply.

HINTS FOR HANDLING
Introduction
Cleanliness is a priority when handling vacuum equipment.
The use of clean, lint- and powder-free gloves (vinyl) is
recommended at all times. Internal surfaces of vacuum
equipment should never be touched without gloves, as
fingerprints will contaminate the system.
Kyocera uses only highly pure materials because raw
material manufacturing processes can influence amaterial's compatibility with vacuum applications.
These hints give you important information about thehandling and cleaning of ceramic-to-metal assemblies.
Hints for ceramic-to-metal components
Flange-mounting is the preferred method of installation
for ceramic-to-metal components. They may also be
welded directly to a chamber if a flange connection is
not feasible. Please take care to avoid undue stress on
the ceramic and the brazing point during the welding
process.
Quality control of ceramic-to-metal components consistsof visual, mechanical inspection of dimensions and leakchecking, as shown in the production drawing, certifi
cates and inspection protocols.
Packing
Protect knife-edges and sealing surfaces with clean
plastic flange caps. Alternatively, wrap them in a double
layer of PE-foil.
During transport, fix movable components(e.g. bellows and rotating flanges).
UHV cleaned ceramic-to-metal components are sealed in
PE bags with desiccants and/or nitrogen.
Alternatively, they can be wrapped in a double layer ofPE-foil.
Avoiding contamination
Avoid contamination of the components during theassembly and welding processes.
Mount and weld in a clean room that is separate fromthe mechanical manufacturing.
Wear clean, lint- and powder free gloves (vinyl) during
the assembly.

Avoiding stress on ceramic-to-metal components
Do not expose the ceramic-to-metal components to
impact loads, bending or thermal stress.
Please take care to avoid undue stress on the ceramic
and the brazing point during the welding process.
Welding
Possible welding methods are:
- Electron beam and laser welding(a minimum distance of 5 mm to the brazing point is recommended)- Metal inert-gas (MIG) and tungsten inert-gas (TIG)(a minimum distance of 10 mm to the brazing point is recommended)

The minimum distance also depends on the construction
and complexity of the ceramic-to-metal assembly. Pleasecontact us for any additional information.
Alternative cooling methods, e.g. copper clamp toprotect the brazing point from too much thermal energy.

Brazed joints
Braze joints only under vacuum or shielding gas
atmosphere.
Only if we know the temperature of the subsequentwelding processes, we can use the correct prebrazing material.
Cleaning ceramic-to-metal components
Clean in a laboratory washing machine by rinsing withalkaline detergent and deionised water.
Use an ultrasonic bath with deionised water and alkaline
detergent.
Perform the ultrasonic cleaning cycles (e.g. 3 times for 5min), interrupted by short rinsing periods (at least 1 min).
Use clean alcohol (e.g. clean isopropanol or similar) toremove surface water or clean glazed surfaces.
Dry by blowing off with dry, oil-free compressed air or
hot air.
Bake-out up to 250 °C (recommended 180 °C; rate of
temperature 5 K/min).
Clean vacuum parts that will be assembled into larger
units in advance. Clean the parts after mechanicalprocessing, taking into account the UHV cleaning requirements.
