Silicon Carbide Seats

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


Silicon Carbide Seats, SiC Seat


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 corrosion from acids. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles, and cyclone components. We provide Silicon carbide seats and other ceramics per request.
