Products

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive to color-based alloys. Silicon metal is a product made from quartz and coke in an electric furnace. The content of silicon in the main composition is about 98% (including 99.99% of silicon is also contained in metallic silicon), and other impurities are iron, aluminum, calcium and so on.

 Application:

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.
