Black silicon carbide is produced at high temperature in anelectric resistance type furnace with quarts sand and petroleumcoke as its main raw materials.
CHARACTORS:
Its hardness is between fused alumina and synathetic diamond.Mechanical intensity of it is hig-her than fused alumina.it isbrittle and sharp and has electrical and heat conductivity in somedegree.
MAIN APPLICATION:
The abrasives made of it are suitable for working on cast iron,non-ferrous metal, rock, leather, rubber, etc. It is also broadlyused as refractory material and metallurgical additive.
Available Specification
SiC Content: 97%,90% etc.
