Superior Quality Transparent/White Fused Silica Sand/Powder for Refractory Materials

Transparent powder is a non-metallic mineral, high transparency, good whiteness, non-toxic, tasteless, acid and corrosion resistant. With transparency, the refraction rate of the filling material itself is very close to the refraction rate of most synthetic resins, so the oil absorption and filling amount are large, which is conducive to reducing the manufacturing cost of the product. The filling amount of the filler does not affect the transparency of the finished product: it can improve the surface smoothness and wear resistance of the product; Low is widely used in oily furniture paint, decoration paint, adhesive, ink, paint and plastic.

    Application

    1.Aluminum smelting: Calcium fluoride as an additive to bauxite, can control the melting point and increase the yield of aluminum.
    2.Metallurgical industry: Calcium fluoride can be used as a flux and slag in the steel and casting industry, which can effectively reduce the oxidation rate and melting point of metals.
    3.Ceramics, glass and glazes: Calcium fluoride can be used as raw materials for ceramics and glass to increase their hardness and transparency, and in products such as glazes and reflective finish paints.
    4.Chemical industry: Calcium fluoride is used in the production of chemicals such as fluoride and fluorocarbons.
    5.Semiconductors, electronics, optics and pharmaceuticals: Calcium fluoride can also be used for material preparation in these fields.
    6.Other fields: Calcium fluoride is also used in the manufacture of special lenses, fluorspar abrasives, and as a raw material for certain optical products.
    7.Light, optical, engraving and defense industries: Calcium fluoride is also used in these industries.
    1.8.Water treatment: Adding calcium fluoride to drinking water can help prevent dental disease, usually in concentrations of 1-1.5ppm.

    Storage and Packaging

    1. Storage: It should be stored in dry, ventilated and cool place to avoid moisture and pollution.
    2. Packing: generally packed in paper bag or plastic bag, also can be customized according to customer's demand.
    Regular Packaging:
    1. bulk bags
