2.13 years professional experience
3.Certification: ISO9001
4.Factory supply
Black /green silicon carbide lump/granule/powder/briquette
for casting
Description:
1.Silicon carbide(SIC) is one type of material with good abrasion resistant property/good chemical stability property/good corrossion resistant property/ good thermal shork resistant property
2..Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is
thermal shock and abrasion resistant and has strength at high temperatures.
3. Silicon carbide is an extremely hard material , is chemically inert and does not melt.
4.Silicon carbide’s varied properties make it an effective material in many different applications.
5.The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond
Application:
1.Silicon carbon can be used as metallurgical deoxidizer and high temperature resistant materials in smelting.
2. 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.
3.For lapping and polishing ,metallurgical additive and refractory material.
4.For grinding, honing, water-jet cutting and sandblasting.
Character:
1.Low density
2.High strength
3.Low thermal expansion
4.High thermal conductivity
5.High hardness
6.High elastic modulus
7.Excellent thermal shock resistance
