Black silicon carbide
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.
Properties of Sic is extreme hardness, high temperature resisting,
chemical erosion resisting, radiation resisting and good electric
conductivity and thermal conductivity, low thermal expansion, it’s
Moh’s hardness is 9-9.5.
Silicon carbon is a new kind of reinforced steel-making deoxidizing
agent and ideal thermal insulating agent.it is used for
deoxidizing. The usage dose is 1-4kg/t can make electricity
consumption to reduce 15-20kw/h and time to reduce 15-20min per
furnace to raise productivity rate to 8-10%.

Application of silicon carbide recycle:
1. Used to grind cast iron, rubber, non-ferrous metals, leather,
plastic, ceramic, wood, rock, etc.
2. Widely used to manufacture high-grade refractory products and
3. Suitable for surface grinding, lapping or polishing.
1).Silicon Carbide is widely used in the fields of Abrasive,
Grinding, Metallurgy, Refractory,Ceramics,
Petroleum,Chemical,Microelectronics,Automobile and Aerospace and so
2).Silicon carbon can be used as metallurgical deoxidizer and high
temperature resistant materials in smelting.
3). It can also be used as abrasive materials,which can be used to
make abrasive tools,such as grinding wheels, oilstones, grinding
head and so on.
The main field of application:
1). Nonferrous metal Smelting industry.
2). Steel line using
3). Energy-saving line
4). Lining of high furnace to improve furnace age.
5). Stemming,downspouting and all kinds refractory brick of high
6). Iining of Electric tank of Electrolytic Aluminium or total tank
body made by sic.
7). Silicon carbide ceramics is made by high quality sic fine
powder,firing several wearproof,acid- resisting and high
temperature resistance parts.
