Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor
Tungsten carbide is approximately two times stiffer than steel, with a Young''s modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum (α-Al 2 O 3 ) or sapphire/ruby in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitrideand diamond, in the form of powder, wheels, and compounds.
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance.
Green Silicon Carbide (SiC) is produced basically in the same process as black silicon carbide in a resistance type electric furnace with petroleum coke, quartz sand and other materials.It is an extremely hard (Knoop 2600 or Mohs 9.4) manufactured material with high thermal conductivity (100 W/m-K).
Oxycarbide glass, also referred to as silicon oxycarbide, is a type of glass that contains oxygen and carbon in addition to silicon dioxide. It is created by substituting some oxygen atoms with carbon atoms. This glass may contain particles of amorphous carbon, and silicon carbide.. .
