DESCRIPTION
Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum. The metallic silicon is silver gray crystal, hard and brittle. It is melted by quartz stone with more than 98.5% SiO2. As a kind of basic industrial raw materials, it is widely used in the production of silicone and polysilicon and mainly applied in aerospace, aviation, electronics, organic chemical industry, smelting, fire-resistant and thermal insulation industries and fields.
