Black silicon carbide
Introduction
SIC 98%.......F.C 0.35%....Fe2o3 0.6%..... Magnetic material content 0.0023%.....color black ……hardness(mohs) 9.15…….ture density 3.9
Marterials: petroleum coke
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials .Its hardness is between fused alumina and synthetic diamond.Mechanical intensity of it is higher than fused alumina .It is brittle and sharp has electrical and heat conductivity in some degree.
