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.
