Silicon Carbide
Lightweight and yet enormously stable – that is what distinguishes silicon carbide. This ceramic material has excellent physical and electronic properties. Products made of silicon carbide are ideally suited for applications in which wear resistance, high rigidity, corrosion and temperature resistance are of essential importance. These include mechanical and plant engineering applications, for example, sliding and sealing rings for pumps and welding rollers and centering pins. In addition, components made of silicon carbide have proven themselves in the semiconductor industry, for example Vacuum Chucks, Integrated Mirrors for Stages, Stage Parts and Frame Parts as well as in the chemical industry, measurement technology and the oil and gas industry.
