Factory Supply High Quality Wash Quartz Silica Sand Price
Description
Silica Sand (with Silica powder), also known as quartz sand.It is a hard, wear-resistant, chemical stability of minerals, the main mineral component is quartz, the main chemical ingredient is SiO2, the color of the powder is white or colorless.
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.
