What is Microsilica Fume?

Microsilica fume, also known as silica fume or microsilica fume, is a material made by collecting and processing the smoke and dust that escapes with the exhaust gas during the high-temperature smelting of industrial silicon and ferrosilicon in industrial electric furnaces. In this smoke, the SiO2 content accounts for about 90% of the total amount of smoke. The particle size is very small, and the average particle size is almost at the nanometer level, hence the name microsilica powder. The main component of microsilica powder is SiO2, which is a non-toxic, odorless and pollution-free inorganic non-metallic functional material. It has good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion and chemical properties. Excellent properties such as stability and high hardness. The production of microsilica powder belongs to the non-metallic mineral products industry and is widely used as raw and auxiliary materials in traditional industries such as building materials, metallurgy, automobiles, chemicals, and light industrial machinery. It is also the support for high-tech industries such as electronic information, new energy, and new materials. Material.
