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. Silicon carbide ceramics maintains its high mechanical strength in temperatures as high as 1400°C It has higher chemical corrosion resistance than other ceramics. Customization is available upon request.
