  • Soft composite silica powder

    Soft composite silica powder

    Soft composite silica powder

    【Explanation】:Soft composite silica powder refers to the glass phase silicon dioxide powder material made of natural quartz and other inorganic non-metallic minerals by such processes as compounding, melting, cooling, crushing, grinding and classifying.

    【Applications】:
