The silica fume is also called microsilica or microsilica fume. When ferroalloy is smelting ferrosilicon and industrial silicon (metal silicon). A lot of volatile SiO2 and Si gases are produced in the submerged arc furnace. After the gas is discharged, it is rapidly oxidized, condensed and precipitated with air. It is a byproduct of large […]
