Silicon micro powder, also known as quartz powder, is made of natural quartz (SiO2) or molten quartz (natural quartz after high temperature melting, cooling amorphous SiO2) by crushing, ball grinding (or vibration, airflow grinding), flotation, pickling purification, high purity water treatment and other multi-channel processing of micro powder Read More »

High purity polysilicon​ material is the basic raw material of information industry and solar photovoltaic power generation industry. Many developed countries regard it as a strategic material. Electronic-grade polysilicon is one of the most basic and main raw materials for manufacturing semiconductor silicon wafers, known as the "food" of the electronic information industry, with purity requirements of 99.999999999% ~ 99.999999999% (9N ~ 11N).
