Quartz Powder

Product Description

Quartz
The term 'quartz' is often referred to as a synonym for silica. Silica (SiO2 ) is one of the ubiquitous materials in the earth's crust. Quartz, quartz crystals, quartzite, silica sand, sand (others) and moulding sand are all coined together in one generic name 'silica minerals'. This is because all these commodities are essentially crystalline silicon dioxide (SiO2 ) with variations mostly related to their crystalline structure and presence of minor or trace impurities. Silica occurs in several forms giving rise to different varieties..
 
Uses
Quartz, quartzite and silica sand are used in various industries like glass, refractory, foundry, ceramic, cosmetic, electrical, abrasives, paints, etc.
 
 
In Ceramics Indusrty, Low-iron ground silica, typically ***0 mesh is used in whiteware formulations to facilitate drying of the body, to control expansion characteristics and compatibility between the body and glaze to prevent crazing, and to provide whiteness and acid resistance.
For Coatings, Quartz is mainly  used as extender pigment because of its low binder demand, which allows high loadings. Quartz used in coatings provides flatting, mar resistance, and abrasion resistance.
 
In Rubber Industry, Quartz powder is used as a compounding agent to promote abrasion resistance, cut growth resistance, tear strength, elastomer-to-textile adhesion, and resistance to heat aging.
In Plastics  Quartz is used as antiblocking and antislip agents by temporarily absorbing plasticizers that can cause tack and by providing an imperceptible surface roughness. They are used as matting or flatting agents and as plate-out agents in highly plasticized compounds. 
In Adhesives and sealants  Quartz in various forms is used in adhesives, caulks, and  sealants to control flow and sag, improve bond strength, and provide reinforcement. Finely ground natural silica is used for its low moisture content, low cost, low binder demand, and its ability to improve tensile strength without affecting flexibility or durability
Other uses, Quartz powder is used as thickeners in printing inks, as carriers for liquid and active ingredients, and as anticaking and moisture control agents. Fumed and precipitated silicas are used in high-temperature silicone greases.
