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.
Silica, or more correctly silicon dioxide SiO2, is one of the most abundant compounds on the surface of the Earth, being most obvious as quartz and common sand. Silica has a multitude of uses depending on the degree of purity. Grades up to 99.5% SiO2 are used in the manufacture of glass, optical fibers and ceramics.
