Silicon Metal Powder is also called industrial silicon powder. It is silver gray or dark gray powder with metallic luster. Of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it’s called ‘industrial glutamate’, which is an essential basic raw material in hi-tech industry.
