INTRODUCE

Silicon powder, also known as micro silicon powder, scientific name is silicon ash, which is formed by collecting and processing the smoke and dust escaping with the exhaust gas in the process of smelting industrial silicon and ferrosilicon at high temperature in industrial electric furnace. In the escaping smoke, the content of SiO2 accounts for about 90% of the total smoke, the particle size is very small, and the average particle size is almost nanometer, so it is called silicon powder.
