Our technologies allow us to produce ceramic insulators for various applications (vacuum chambers, power semiconductor devices, image intensifying tubes) and ceramic tubes as well as other ceramic products for variety of industries. The products are manufactured of various types of vacuum tight ceramics that feature high values of electric resistance, mechanical strength, and dielectric properties.
Ceramic
insulators are applied in vacuum arch quenching
chambers that are further installed in
vacuum breakers and load interrupters used in switch gear of
electric mains (*-phase AC, *0 and *0 Hz).
nsulators for power semiconductor devices
housings are
used in power semiconductor devices (diodes and thyristors)
of high voltage converters.
Image intensifying tubes are
used as electro insulating part of military
night vision devices for. The key part of the night
vision device is an image intensifying tube that intensifies the
light and converts infrared light into visible.
Metal coatings provide a possibility for copper, stainless steel and Nickel brazing at temperature of ******0 0C.
Types of metal coatings: Nickel (***2 μm), Copper (****0 μm). Copper coating is at the stage of development.
Metal coatings are applied on an intermediate metal layer.
Following types of the intermediate metal layer are available: Mo-Mn-Si (****5 μm).
Min Ceramic-Metal adhesion strength is **0 N/mm2.
