Product Description

SUOYI Si Powder Silicon CAS 7440-21-3 for concrete with Factory price

Silica powder, also known as microsilica powder, scientifically known as silica fume, is the smoke and dust that escapes with the exhaust gas during the high-temperature smelting of industrial silicon and ferrosilicon in industrial electric furnaces, and is collected and processed by special capture devices. In the escaped smoke and dust, the SiO2 content accounts for about 90% of the total smoke and dust, and the particle size is very small, and the average particle size is almost nanometer level, so it is called silica powder.
