● Introduction
The graphite susceptor with SIC coating has such good characteristics as high temperature resistance, oxidation resistance, high purity, good corrosion resistance of acid, alkali and organic solvent, and stable physical and chemical properties. High purity graphite can be oxidized strongly at the beginning of 400℃. Even in mild temperature, the high purity graphite also can be oxidized in the process of its usage. Thus, the graphite susceptor with SIC coating will gradually take the place of the high purity graphite in MOCVD and other application areas.
● Characteristics
1. Excellent oxidation resistance at 1600℃.
2. High purity.
3. High hardness,the surface is of dense, fine particles.
4. Corrosion-resistance.
5. The surface layer is β-SIC.
