silicon metal is used for refractory,we are the manufacturer to export it 5000 tons per month with high quality and good price
Production Description:
Industrial silicon , which can also be called metal silicon ,is silver grey or black with metallic luster. It has the function of high melting point, good heat resistance, high oxidation resistance, high resistivity.It is the essential basic raw materials of many high-tech industries.
Application
(1) Widely used in industrial refractories, powder metallurgy industry, and improve the product temperature, wear and oxidation resistance.
(2) In the organic silicon chemical industry,the industrial silicon powder is the basic raw materials of organosilicon polymer material.
