Cast Refrax

Silicon nitride bonded silicon carbide

Cast Refrax silicon-nitride-bonded silicon carbide refractory is chemically inert to most materials. Its extreme hardness provides outstanding erosion resistance. The manufacturing methods allow complex geometrical shapes to be produced. It is ideal for use in high wear applications like launders and degassing rotors.

  • Life spans much longer than alternative materials (e.g. graphite, refractory metals, refractory cements)
  • Dimensional stability over the lifetime of the component
  • Compatible with complex part geometries 
  • High thermal shock resistance 
  • Extreme hardness and anti-wear characteristics 
  • Resistance to oxidation and chemical attack at elevated temperatures
