First of all, 97 silicon powder, also known as micro 97 silicon powder, is the smoke and dust recovered in the process of processing 97 silicon metal or iron alloy. Because it is rich in silica and its high activity, it is widely used in concrete, refractory materials, rubber, paint and other fields.
Then, the main component of 97 silicon metal powder is crystalline silicon. At first it is lumpy or granular, after various degrees of crushing and grinding into powder. Mainly used in the field of refractory production.
97 silicon metal powder is made by physical grinding, and its chemical composition is quite different from that of 97 silicon powder recovered in production. The main component of 97 silicon powder is silicon dioxide, and the main component of 97 metal silicon is silicon. 97 silicon metal powder is generally inactive, while 97 silicon powder has pozzolanic activity. The color of 97 silicon metal powder is usually relatively stable, while the color of 97 silicon powder changes greatly from white to black; 97 silicon powder is widely used.
The above is the difference between the two and their different uses. If you want to know more about it or purchase 97 silicon metal powder, please send an email to shengchi ferroalloy. Our website: http://www.scferroalloy.com/
