Leading Quality Silicon Metal 553 421 1101 As Alloy Additives
Metallic silicon, also known as metallurgical-grade silicon or simply metallurgical silicon, is a form of silicon that is primarily used in the production of aluminum alloys and silicones. It is produced through the reduction of silica (SiO2) with carbon in an electric arc furnace, resulting in a high-purity silicon product.
It can alloy with certain metals, such as iron, to form silicon-iron alloys.
Product Details
Silicon Metal is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high
resistivity and superior oxidation resistance.
Silicon Metal processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It is silver gray or dark gray powder with metallic luster, which be 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.
