si powder
Description
Industrial silicon powder is also called as silicon metal powder, it is silver gray or dark gray powder with metallic luster.
With the characteristic of high melting point, good heat resistance, high resistivity and high antioxidant effect, it is Known as "industrial MSG"- indispensable basic raw materials to many high-tech industry.
