Silicon powder is a non-toxic, tasteless, non-polluting non-metallic mineral powder, made from natural quartz or fused quartz by crushing, ball milling (or vibrating, air milling), flotation, acid pickling purification, high-purity water treatment and other processing. It has the characteristics of high hardness, low oil absorption, easy to disperse, not easy to precipitate, strong stability, acid corrosion resistant, and so on. Therefore, it is widely used in chemicals, electronics, integrated circuit (IC), electrical appliances, plastics, coatings, advanced paints, rubber, national defense and other fields. With the rapid development of high-tech field, Silicon dioxide micropowder will also enter a new period of historical development.
