Metallic Silicon Powder industrial silicon

Product Performance

Metallic silicon powder, also known as industrial silicon powder, is processed from high-purity metallic silicon blocks. The powder appears silver-gray or dark gray with a metallic luster. It features a high melting point, excellent heat resistance, high resistivity, and strong oxidation resistance.

Often referred to as the "MSG of Industry" — an indispensable fundamental material across many high-tech industries.
