Product Description

 

 

Product Description

Silicon carbide is a non-metallic mineral product produced at high temperatures above 1800 degrees Celsius with quartz sand (SiO2) and anthracite or petroleum coke (C) as basic raw materials.It has the characteristics of high hardness, small expansion coefficient, brittleness, good thermal conductivity, etc., widely used in abrasive abrasives, electronic products grinding, refractory materials, special ceramics, foam ceramics, coating plastic addition modification, auto parts, military aviation, steel deoxidizer. The company mainly produces various content specifications of black silicon carbide

 Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. Silicon carbide rough materials can be supplied in large quantities and cannot be considered high-tech products. However, the application of nano-scale silicon carbide powder with extremely high technical content is unlikely to achieve economies of scale in a short time.
*As an abrasive, it can be used to make abrasive tools, such as grinding wheels, oil stones, grinding heads, sand tiles, etc.

*As metallurgical deoxidizer and high temperature resistant material.

*High-purity single crystal can be used to manufacture semiconductors and silicon carbide fibers. Main uses: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.

Packaging & Shipping

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive 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.
