Our company provides SiC coating process services on the surface of graphite, ceramics and other materials by CVD method, so that special gases containing carbon and silicon can react at high temperature to obtain high-purity Sic molecules, which can be deposited on the surface of coated materials to form a SiC protective layer for barrel type hy pnotic.
Main features:
1 .High purity SiC coated graphite
2. Superior heat resistance & thermal uniformity
3. Fine SiC crystal coated for a smooth surface
4. High durability against chemical cleaning
