TECHNICAL INFORMATIONNanoparticle, Nano Colloids Oxide Materials(ZrO2, CeO2, TiO2, Fe3O4, WO3 etc…)
We have developed FUJI NP Oxide series as Nanoparticle, Nano ColloidsOxide Materials, based on years of our experience in the field of organic pigment,functional material manufacturing technology, industrial powder fine grinding,nano size particle dispersion technique.

FUJI NP Oxide Series are madebased on either dispersion or synthetic technology.

When metal,semiconductor, oxides becomes in a range of nano size (0.5 – 30 nm), theyexhibits different physical and chemical properties compared to bulk materials.
They behave in a different way even they are same materials when particle size
is extremely small, such as
1. Quantum size effect
2. Electronic devices can be thinner and smaller
3. High activity due to enhanced surface area
4. Enhancement of solubility, diffusion speed in a liquid
5. Enhancement of memory function
6. Melting, sintering temperature can be lowered
7. Enhancement of emission intensity
8. Enhancement of catalysis, new reaction pathway
These phenomenon are due to various influence of quantum size effectincluding high surface area, interface area, enhancement of diffusion speed,solubility of molecules.
For rapidly developing modern scientific technologies, various types of devices
have tendency to become smaller, lighter, finer resolution, higher density.
Utilizing these properties, nano particle, nano colloids oxide materials can beapplied for modifier for nano sized structural ceramic, thin film synthesis, coating,materials for rechargeable battery, fuel cell, solar cell, fluorescent material,

TECHNICAL INFORMATION

encapsulation material, filler for various types of films, paint, catalyst, pigment,
absorbing material, abrasive material, electronic material, magnetic, storage
material, sensor, cosmetics, drug delivery, artificial tissue etc… so many
applications can be expected.
In our company, to correspond to imminent society demands for these nanoparticles, nano colloids materials, we have been developing and manufacturing
various types of oxide materials.
Main solvent is usually water, although we can replace with other organic
solvent if customer requests.

For example, above figure indicates the particle distribution of water based CeO2
nanoparticle, nano colloids. Based on this, we can also prepare ink, slurry forvarious type of customer purpose.

Below table presents the basic propertiesof water based CeO2 nano particles colloids.

TECHNICAL INFORMATION

FUJI NP CeO2 series

0.2 – 5.0 %Resin and additive

0.1 – 4.0 %Water or Organic Solvent (Terpineol,

90.0 - 99.0 %NMP, MIBK, Toluene, BCA etc…)

1.0 – 80 mPa・s/ 25 °C
Viscosity(Viscosity can be modified for customer’s request
for their printing method)

Particle size of FUJI NP CeO2 series

0.5 nm – 5.0 nm

It is critical when nano particle, colloids are mixed with various types of additive,
resin, solvent etc.. in order to make ink, slurry.

Because sometimes they candeteriorates the stabilized nano particle dispersion in a liquid.

However, basedon our long termed liquid dispersion technologies, we will try to prepare good ink,slurry for customer demands. We are also now developing SiO2, Al2O3,ZnO
etc… besides our current items ZrO2, CeO2, TiO2, Fe3O4, WO3 nano particle,colloids.
Please consult with us including any technical detail anytime.
Thank you in advance.
