Silica Quartz Sand

タイトルまたは説明

1 Statement:

Being of the special physical and chemical properties, quartzite occupies an important position in the application of astronautics, electronics, machinery and the IT which is developing by leaps in recent years, especially in metallurgy industry.

With the structure of the molecular chain, form of crystal and varying regular of crystal lattice, quartz is of high temperature resistance, small thermal expansion coefficient, high insulation, corrosion preventive, piezoelectric effect and resonance effect. And with the special optical property, quartz plays an important role in high-tech products.

We are professionally in manufacturing and selling all kinds of quartzite such as high purity quartzite, refining quartzite, common quartzite, molding sand, metallurgy quartzite, quartzite being specially used to medium frequency furnace and furnace liner quartzite and so on. The content of SiO2 in several of quartzite is equal or greater than *9%**9.5%, and Fe2O3 is equal or less than 0.*2%*0.**5%. The size of quartzite is able to customize according to the need of the customers in range of *0mm maximum and **0mesh minimum, and the appearance is white powder or crystal.

Physical state: our company's quartzite is made of natural quartz roes after crushing, sieving and water scrubbing and takes on multi-prismatic shape and pure white color with no impurity.

 2.Application:

Glassmaking; Refractory; Ferrosilicon Smelting; Solvent metallurgy;

Pottery and Porcelain; Abrasive; Foundry; and so on

Quartzite plays an irreplaceable foundation role in production and supply of silicon product as the raw material.
