Published: February 2021

The prospects for use of glass-ceramic materials as electrical products were analyzed. The priority of a self-organized macro- and nanostructure formation of the glass-ceramic materials under conditions of low-temperature heat treatment to ensure their high physical and chemical properties was shown. The choice of an alumina silicate system of materials for obtaining high-strength glass-ceramic materials with improved electrical properties was substantiated, taking into account the aspects of energy saving. The technological modes of cooking, forming and heat treatment of glass-ceramic materials were determined.
Resistance, dielectric constant and dielectric loss tangent at 106 Hz were measured using an E6-13A teraometer on a trielectrode system at a temperature of +29 °C and a DE-5000 RLC meter. Electric strength (Em) and cold crushing strength were determined according to GOST 24409-80. Tensile strength according to GOST 32281.1-2013 (EN 1288-1: 2000).
The decisive influence on the electrical properties of glass-ceramic materials the crystalline phases of α-cordierite, β-spodumene or lithium disilicate, as well as the residual glass phase composition has been established. The structure influence of the alumina silicate glass-ceramic materials on the provision of their electrical (tgδ∙104 = 70 ÷ 80; ε = 8.0 ÷ 9.3 (at f = 106 Hz); lg ρv = 12.9 ÷ 15.0 (ρv, Ohm·cm at Т = 20 °C) and mechanical (K1C = 3.15 ÷ 4.3 МPа∙м1/2; σ comp = 630 ÷ 700 МPа, σbend = 300 ÷ 350 МPа; KCU = 4.8 ÷ 5.9 kJ/m2) properties.
It was found that, the defining condition for the developed glass-ceramic materials use as insulating materials under repeated exposure to high-temperature operations is their high breakdown strength Em = 37 ÷ 42 MV/m and thermal shock resistance due to low TCLE (α∙107 = 21.5 ÷ 31.8 deg-1).
The influence of phase composition and structure of the alumina silicate glass-ceramic materials on their electrical and mechanical properties was analyzed. A comparative assessment of the known ceramic and glass-ceramic materials for electrical purposes has made it possible to establish the feasibility of using the developed materials as substrates in the design of a hybrid integrated circuit, vacuum-tight shell and capacitor dielectrics.
Sol - gel method for producing of glass binding in the Li2O - Al2O3 - SiO2 system for ceramic materials
Authors: Khomenko E. S. , Karasik E. V. 
Published: February 2021

The results of glass binding obtaining in the Li2O — Al2O3 — SiO2 system for ceramic materials are presented in the article. The lithium aluminum silicate system was chosen taking into account the low temperature expansion coefficients of crystalline phases that form in it. This will allow controlling the thermal expansion of materials into which the glass binding will be introduced. A sol - gel method based on ethyl silicate and soluble salts of the corresponding oxides is proposed as a method for producing of glass binding. This method is more rational in comparison with the traditional method of glass melting due to low energy costs. Also, the method allows to obtain a more uniform and active product.
The effect of glass binding on the properties of ceramic materials for various purposes has been investigated. As such materials, low-temperature electrotechnical porcelain, quartz ceramics, and engobe coatings were chosen. The glass binding was introduced into the raw material charge of these materials in an amount of 5 wt. %. Further, the properties of calcined product without additives and with additives under the same conditions were compared.
The intense fluxing effect of glass binding during the formation of electrical porcelain has been established. The glass binding reinforces the effect of natural fluxes (pegmatites) that are present in the basic composition of the mass. This contributes to the material compaction during firing. The formation of eucryptite and spodumene helps to reduce the thermal expansion of material. The introduction of glass binding into the engobe led to a less intense compaction of its structure. This was observed due to an insufficient amount of the added glass binding for this type of material. In the composition of quartz ceramics, glass binding contributed to the material sintering, but the thermal properties were deteriorated.
Thus, the sintering results of ceramic material with the introduction of glass binding in the charge composition are positive. However, sintering significantly depends on the material type. The glass binding stimulates the formation of a melt in which solid finely dispersed components of the ceramic mass dissolve. This contributes to the formation of a dense durable ceramic.

Chili is one of the most important foods for traditional Indonesian food. One of the chilies that have a very high Scoville rating from Toraja Utara and Tana Toraja is Cabe Bakul or Lada Katokkon. This chili is different from other peppers ranging from the shape that resembles a pabrika but the size is small, it is sweet taste turned hot and good smelled. . The disadvantage of this chili is the condition of chilies that have a very high water content so it is easy to rot and wrestle so that the price quickly goes down and sometimes thrown away. To avoid the problem, the team proposes to process chili into a product but does not change the taste, color, and smell. This activity helps the chili farmers to process their crops into processed products that have higher economic value. There are two types of products produced are Chili powder (Bon Cabe) and sauce. Chili sauce is made there are four variants of flavors are: original, onion, terasi, and fish. Through this training, the farmer group partners can cultivate the harvest and its products can compete in the Toraja market and outside Toraja.
Abstrak
Cabe merupakan salah satu makanan terpenting untuk makanan tradisional Indonesia. Salah satu cabai yang memiliki rating Scoville sangat tinggi dari Toraja Utara dan Tana Toraja adalah Cabe Bakul atau Cabe Katokkon. Cabe ini berbeda dengan cabe lainnya mulai dari bentuknya yang menyerupai pabrika namun ukurannya kecil, rasanya manis berubah menjadi panas dan harum. Kekurangan dari cabe ini adalah kondisi buah cabe yang memiliki kandungan air yang sangat tinggi sehingga mudah membusuk dan bergelut sehingga harganya cepat turun dan kadang dibuang begitu saja. Untuk menghindari masalah tersebut, tim mengusulkan untuk mengolah cabe menjadi sebuah produk namun tidak merubah rasa, warna dan baunya. Kegiatan ini membantu petani cabe mengolah hasil panennya menjadi produk olahan yang memiliki nilai ekonomi lebih tinggi. Ada dua jenis produk yang dihasilkan yaitu bubuk cabe (Bon Cabe) dan saos. Kuah sambal yang dibuat ada empat varian rasa yaitu: original, bawang, terasi dan ikan. Melalui pelatihan ini para mitra kelompok tani dapat membudidayakan hasil panen dan produknya dapat bersaing di pasar Toraja dan luar Toraja.
