Sericite powder is natural mica powder. It has the property of chemical stability, ageing resistance, acid and alkali resistance, anti-ultraviolet, insulation and silk luster. Our company chooses high quality mine ore, with the process of primary crushing, high pressure crushing and classification processing to ensure the quality of sericite powder. It has the property of large diameter-thick ratio, good lamellar structure and high purity.
