DESCRIPTION
Pure silicon powder, also known as industrial silicon, is obtained by the reduction of silica (SiO2) by carbonaceous reducing agents (petroleum coke, washed coal, charcoal, etc.) in a mineral-heating furnace, with a silicon content of not less than 98.7%. After the metal silicon is smelted, the metal silicon is ground into powder according to the needs of the producer.
●Pure silicon powder is widely used in refractory materials and powder materials metallurgy industry to improve the high-temperature resistance, wear resistance, and oxidation resistance of products. Its products are widely used in steel furnaces and kilns.
●Silicon metal powder can be made into silicon wafers, which are widely used in high-tech fields and are indispensable raw materials for integrated circuits and electronic components.
●In the metallurgical industry, pure silicon powder is used as a non-ferrous alloy additive and silicon steel alloy to improve the hardness of steel.
