Microsilica/Silica Fume

Silica fume (microsilica or silica fume), also known as micro silica fume, with the scientific name of "silica fume", is formed by collecting and treating the smoke and dust escaping with the waste gas in the process of smelting industrial silicon and ferrosilicon at high temperature in the industrial electric furnace. The scientific name "silica fume", microsilica or silica fume, is formed by collecting and treating the smoke and dust escaping with the waste gas in the process of smelting industrial silicon and ferrosilicon in an industrial electric furnace at high temperature. In the escaping smoke and dust, the content of SiO2 accounts for about 90% of the total smoke and dust. The particle size is very small, and the average particle size is almost nanometer, so it is called silicon powder.
