Product Overview

Industrial Silicon Powder — The "Industrial MSG"

Silicon metal powder, also called industrial silicon powder, is processed from selected silicon metal lump. The powder is silver-grey to dark grey with a metallic luster. It offers a high melting point, excellent heat resistance, high electrical resistivity and strong oxidation resistance — an essential base material for many high-tech industries.
