Main characteristics of the manufactured product

Porous ceramicsunique development

Our enterprise has developed a unique technology for producing products from oxide-beryllium ceramics of nuclear grade according to ASTM C708-16.

Ceramic porosity can reach 90%, pore size from 10 to 200 microns. The developed technology allows to provide stability of ceramic density readings within ±0.1 g/cm3. Stability of geometric sizes estimated by measuring the change of density before and after heat treatment at temperature of 1773 ºK with dwell time not less than 24 hours amounts to less than 1%.

This material is used in the construction of a nuclear reactor, for effective removal of heat released due to fission of uranium dioxide nuclei, or as a moderator and reflector of neutrons in nuclear power installations.

In 2021 our company successfully passed certification and supplied porous oxide-beryllium ceramics of nuclear purity for the Korean company KAERI, which is the only research institute in Korea specializing in nuclear energy.

Black ceramicunique development

For high-power TWL devices (traveling wave lamps) it is necessary to create microwave absorbing materials of increased thermal conductivity. For this purpose it is necessary to use high thermal conductivity composite ceramics, one of the components of which must be well pass microwave radiation, and the other absorb. One of such promising materials manufactured by "KAZ CERAMICS" LLP is ceramics containing BeO and TiO2 powder. Produced bulk microwave energy absorbers in addition to the absorption properties and high thermal conductivity have structural stability, homogeneity of electrical properties, stability of properties in a wide temperature range. As a result of sintering in a reducing hydrogen environment of oxide-beryllium ceramics with the addition of TiO2 micropowders, its density and electrical conductivity increase, the ability to absorb electromagnetic radiation in a wide frequency range appears. The most effective material is the composition in which the mass content of TiO2 in the BeO ceramic is 30 wt.%, that is, BeO + 30 % TiO2, (hereafter % by mass). Such ceramics are called BT-30. The attenuation factor of microwave radiation passing through the ( ВеО + TiO2)-ceramics in the frequency range of 8.5 - 12 GHz is 19 - 20 dB. The increase in the carbon admixture in the ceramics is accompanied by an increase in the electrical conductivity of ( ВеО + TiO2)-ceramics.
