Black silicon carbide is non-metallic mineral products, with quartz sand (SiO2) and anthracite or petroleum coke (c) as the basic raw materials, generated at a high temperature above 1800° C.
It has high hardness, small expansion coefficient, crisp and good thermal conductivity characteristics, extensively used in abrasives, electronics, abrasive, refractory materials, special ceramics, ceramic foam, auto parts, military aviation, steel making, deoxidation agent.
The applications of black silicon carbide powder are increasing wider and wider and there is a further demand for black silicon carbide powder.
Our company has used dry, wet, dry and wet combining method to produce the black silicon carbide powder to apply to the different needs of different products.
Products are mainly used in the manufacture of refractory products, ceramic foam industry, solar silicon panels cut, crystal cut grinding, automotive original equipment manufacture, special coatings, plastics modification, environmentally friendly desulfurization power supply industries.
Black silicon carbide is made through the crushing, grinding, acid-base wash, washing, drying, screening and other techniques of natural blocks, our standardized products can meet the different needs of customs.
Production standards include the Chinese standard, international standard, Japanese standard, and European standard.
The European standard product model our company produces is as follows:
F6, F8, F10, F12, F16, F18, F20, F22, F24, F30, F36, F40, F46, F54, F60, F70, F80, F90, F100, F120, F150, F180, F220, F240.
