What is the use and performance of spherical silica powder

  Silica powder  is an odorless, pollution-free inorganic non-metallic material. Because of its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in chemicals, electronics, integrated circuits (IC), electrical appliances, Plastics, coatings, high-quality paints, rubber, national defense and other fields. With the rapid development of high-tech fields, silicon powder will also enter a new historical development period. Silicon dioxide powder  is made of natural quartz ( SiO2 ) or fused quartz (amorphous SiO2 after high temperature melting and cooling of natural quartz) after crushing, ball milling (or vibration, jet milling), flotation, pickling purification, high-purity water treatment, etc. Micro powder processed by the technology. Spherical silicon micropowder is mainly used for the packaging of large-s...
