Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It's known as the 'salt' of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.
Silicon Metal lump was produced in electric heating furnace by quartz and coke. Quartz will be redox and became molten silicon liquid. After cooling, it will be solid as we see. The primal silicon metal lump is very large. Then it will be made
into smaller lumps which we call standard size. Silicon Metal Lumps will be 10-100mm.
It is silver gray or dark gray with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance.
1) Silicon Metal is widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
2) In the chemical line of organic silicon, industrial silicon powder is the basic raw material for the formation of high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, extensively used in the high-tech field as an essential raw material for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder serves as an iron base alloy additive and the pharmaceutical alloy of silicon steel, enhancing the hardenability of steel.
5) Silicon metal is used in the production of high-temperature materials.
Our main products include ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, silicon aluminum barium calcium, silicon barium calcium, etc. The company also engages in the export of refractory materials and other metallurgical products. We offer product customization based on customer requirements.
