Properties of Silicon Carbide (SSiC / SiSiC)

• Low density (3.07 to 3.15 g/cm³)
• High hardness (HV10 ≥ 2,200 GPa)
• High thermal conductivity (120 to 200 W/mK)
• Low coefficient of linear expansion 
  (3.6 to 4.1x10^-6/K at 20 to 400°C)
• Excellent thermal shock resistance of SiSiC: ΔT 1,100 K
• Corrosion and wear resistant even at high temperatures

Silicon carbide behaves almost like a diamond. It is not only the lightest, but also the hardest ceramic material and has excellent thermal conductivity, low thermal expansion and is very resistant to acid.

These material properties make silicon carbide predestined for use as a construction material. Silicon carbide masters corrosion, abrasion and erosion as skillfully as it stands up to frictional wear. 

Compared to metals, silicon carbide enables highly economical solutions with longer tool life when used with aggressive, high-temperature media. Silicon carbide ceramics are also ideal for use in demanding conditions in ballistics, chemical production, energy technology, paper manufacturing and as pipe system components.
