Low density and high strength; 
  Good resistance to high temperature; 
  Good wear resistance and anti-friction properties; 
  Excellent resistance to sudden changes in temperature; 
  Good chemical resistance and oxidation resistance; 
  Low thermal expansion and high thermal conductivity (superior to steel); 
  Good electrical conductivity.

  Fixed and moving turbine component; 
  Seals, bearings, pump vanes, ball valve parts; 
  To be used in refractory industry and metallurgical industry, e.g. kiln furniture, etc; 
  Heat exchanger, e.g. electric heat elements, etc; 
 Semiconductor water processing equipment, e.g. wire saw, polishing plates for semiconductor wafer; 
 Due to its high hardness and brittle granular, it is used as abrasive agent, grinding wheel, sandpaper etc. in abrasive field, and as sharpening abrasive on wood and metal; 
 Other using; lightening arresters, wear components for paper-making machines, special seals for chemical processing industry, etc.
