    High purity factory price silicon powder

    Product Description

    ?

    ? ? ? ? ? ? ??Silicon powder is the powder made of natural quartz silica (SiO2) or fused silica (Natural Quartz by melting temperature, cooling after the amorphous SiO2) by crushing, ball milling (or vibration, jet mill, flotation, acid purification, high purity water treatment by multi-channel process. [1] silica powder is a kind of non-toxic, tasteless, non polluting inorganic non metallic materials. Because it has temperature resistance good, acid alkali corrosion resistance, poor thermal conductivity, high insulation, low coefficient of thermal expansion (CTE), chemical stability, high hardness excellent properties, is widely used in chemical industry, electronics, integrated circuit (IC), electrical appliances, plastic, coating, high grade paint, rubber, defense and other fields. With the rapid development of the high technology field, the silicon powder will also enter into a new historical development period.
