Silicon Carbide Plate

Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Silicon Carbide (SiC) Plate.


Silicon Carbide Plate, SiC Ceramic Plates


Edgetech Industries, advanced ceramics division provides sintered SiC plates, reaction-bonded SiC plates and recrystallized SiC plates. Our recrystallized SiC products have high purity, while our reaction-bonded and sintered silicon carbide balls have high mechanical strength.

Silicon carbide (SiC) is a lightweight ceramic material with high-strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to acid corrosion. Silicon carbide is an excellent ceramic material suitable for applications requiring good corrosion resistance and wear resistance.
