Properties:

Industrial silicon (also named Silicon Metal),is a kind of silver gray or dark gray powder with metallic luster.Featured by high fusing point,good heat-resistance,high resistivity and high anti-oxidation.It is well known as "industrial monosodium glutamate" and an indispensable raw material in hi-tech industry.

Applications:

Mainly used for silicon piece of silicon powder series, aluminum alloy ingot smelting steel, aluminum alloy material, and special steel smelting and other products.
