Product Description

Our company provides SiC coating process services by CVD method on the surface of graphite, ceramics and other materials, so that special gases containing carbon and silicon react at high temperature to obtain high purity SiC molecules, molecules deposited on the surface of the coated materials, forming SIC protective layer.

Main features:

1. High temperature oxidation resistance:

the oxidation resistance is still very good when the temperature is as high as 1600 C.

2. High purity : made by chemical vapor deposition under high temperature chlorination condition.

3. Erosion resistance: high hardness, compact surface, fine particles.

4. Corrosion resistance: acid, alkali, salt and organic reagents.
