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. In addition, components made of silicon carbide have proven themselves in the semiconductor and chemical industry as well as in measurement technology and the oil and gas industry. 

The most important material properties of sintered silicon carbide (SSiC) in brief:

  • Excellent chemical resistance
  • High strength
  • Outstanding corrosion resistance, even at very high application temperatures
  • Superior mechanical high-temperature properties
  • Good thermal shock resistance
  • Low thermal expansion
  • Very high thermal conductivity
  • High wear resistance
  • Very high stiffness

The most important material properties of silicon-infiltrated silicon carbide (SiSiC) in brief:

  • High strength
  • Corrosion resistance, even at very high application temperatures
  • Excellent mechanical high-temperature properties
  • Great thermal shock resistance
  • Low thermal expansion
  • Very high thermal conductivity
  • High wear resistance
  • Very high stiffness
  • Capable of very high aspect ratios and thicknesses up to 2 mm
  • Outstanding properties for EDM machining of microstructures below 1 mm due to high electrical conductivity
  • Monolithic homogeneous SiSiC produced by milling from an isostatically pressed block with maximum dimensions of up to 3500 mm x 900 mm x 900 mm
