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.
--RUBBER, PLASTIC: as the filler material for enhancing wear resistance.
--COATING: as the filler material for enhancing weathering resistance.
