What is microsilicon powder?

Micro silica powder is also called silica fume or condensed silica fume, mostly produced in Yunnan, Sichuan, Henan, Shandong, and other places is ferroalloy in smelting ferrosilicon and industrial silicon (silicon metal), ore thermal furnace produced a large number of highly volatile SiO2 and Si gas, gas emission and air oxidation condensation precipitate quickly. It is a by-product in large industrial smelting, the whole process needs to be recycled with dust removal equipment because the density is small, but also need to use encryption equipment for encryption.

Microsilicon powder is gray or white, belongs to no crystal system, mostly from natural quartz processing into larger particle size, 200 mesh, 300 mesh, 400 mesh, 500 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, 3000 mesh, 5000 mesh, 10000 mesh is a powder state. Silicon powder is mainly used in cement, concrete, refractory materials, rubber, chemical dispersant, and other fields.
