Silicon carbide ceramic tube

  • Shape and size can be customized according to requirements
  • Very high hardness(HV10): 22.2(Gpa)
  • Very low density (3.10-3.20 g/cm³)
  • At temperatures up to 1400 ℃, SiC can even maintain its strength
  • Because of its chemical and physical stability, SiC has high hardness and corrosion resistance.

Silicon Carbide

The properties of silicon carbide are very similar to diamond. It is one of the lightest, hardest and strongest industrial ceramic materials. The material of silicon carbide ceramics can be stable at high temperature up to 1400 ° C. Young’s modulus above 400 GPA ensures excellent dimensional stability. The excellent resistance of silicon carbide to corrosion, wear and erosion is as good as its ability to withstand friction and wear.

Silicon carbide is toxicologically safe and can be used in food industry. Another typical application of silicon carbide components is the use of friction bearing dynamic sealing technology and mechanical seals, such as in pumps and transmission systems. When used with active high temperature media, SiC can achieve extremely economical solutions and longer tool life than metals. SiC ceramics are also very suitable for the harsh conditions in ballistic missiles, chemical production, energy technology, papermaking, and as pipeline system components.
