Silicon carbide –

StarCeram S und StarCeram Si

Light and yet incredibly stable – that’s the difference with silicon carbide. Also known as carborundum, this ceramic material has excellent properties for a wide range of applications. Components made from silicon carbide are ideal for applications in which resistance to wear, high rigidity, corrosion resistance and thermal stability are vitally important. With these properties, components can be used in applications including machine and plant engineering, for example, as sliding and sealing rings for pumps. Components made from silicon carbide have also proven their effectiveness in the semiconductor and chemical industry, as well as in metrology and the oil and gas industry. What makes our StarCeram S and StarCeram Si so successful? Excellent material properties with a huge number of benefits.
