Silicon Carbide Plates

Silicon carbide plates is made of SiC materials which is a lightweight ceramic material with high strength properties comparable to diamond. It has high thermal conductivity, low thermal expansion, thermal shock resistance, oxidation resistance, and corrosion resistance. We produce sintered silicon carbide plates, reaction bonded SiC ceramic plates and recrystallized SiC plates.  Its has high purity, grain size consistency and precision grinding.

Product Features:

Good thermal shock resistance
Good resistance against corrosion and oxdiation
Good mechanical strength at high temperature
Excellent thermal and electric conductivity
Long service life and energy saving
Environmental friendly
