Black Silicon Carbide for Sandblasting and Abrasives:

1. brief introduction:

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synathetic diamond. Mechanical intensity of it is hig-her than fused alumina.it is brittle and sharp and has electrical and heat conductivity in some degree.

 2.purity:sic98.5%

4.usage:

1) It can be used into advanced refractories which are added with silicon carbide have thermal shock resistance, compact size, light strength and good energy effeciency. Low grade silicon carbde is an excellent deoxidizer.

2) It can speed up steel making, produce reactive heat energy to reduce energy consumption. In addition, it is convenient for controlling chemical conposition and enhancing steel quality.
