    PROPERTIES

    --Silica sand is a kind of hard and wearable silicic acid mineral with stable chemical properties. It is ivory or without color and translucent.

    --The main component is SiO2 ,hardness is 7 and relative density is 2.65. Silica sand is not dissoluble in acid, melting point is 1750.c.

    ?

    APPLICATION

    Because of special physical properties, chemical properties and strong resistance to acid medium, the silica sands play an important role in many applications as below:

    --GLASS: primary materials for sheet glass, glass products (glass pot, glass tube, etc), fiberglass, glass cloth, ect.

    --CERAMIC AND FIRE-PROOF MATERIAL.

    --METALLURGY: as chemical additive or melting agent for silicon metal, ferro-silicon alloy, ect.

    --CONSTRUCTION: Concretes, road material, artificial marble, ect.

    --CHEMICAL INDUSTRY: raw material of Silicon compound and sodium silicate, etc.

    --MACHINERY: primary materials for Casting molding sand, abrasive substance (sand blasting, sandpaper, etc.)

    --ELECTRON: for the high-purity metallic silicon, optical fiber, etc.
