Metal silicon powder manufacturers tell you what is the difference between metal silicon powder and silicon powder? 

Metal silicon powder manufacturers tell you that the main component of whole silicon powder is crystalline silicon, which is a powder formed after grinding and is mainly used in my country's refractory industry; the main component of silicon powder is silicon dioxide, which is formed during the production process and is the smoke recovered during the whole silicon production process; the color of whole calcium powder is black and is not easy to change; the color of silicon powder ranges from white to black, and the difference between the two is very large.
