DESCRIPTION
Silicon carbide (SiC) from ZhenAn is made from quartz sand and petroleum coke or coal tar, wood chips and other raw materials by smelting in high temperature electric resistance furnace . In the high technology non-oxide refractory raw materials , such as C, N, B ,ilicon carbide is the most widely used and one of the most economic material. It can be called corundum or refractory sand. It is brittle and sharp has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc. It is also broadly used as refractory material and metallurgical additive.
