Quartz sand is the quartz writing processing of quartz grain, quartz is a kind of non-metallic minerals, is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, quartz sand color for the milky white or colorless translucent, mohs hardness 7, quartz sand is important industrial mineral raw materials, the hazardous chemicals, widely used in glass, foundry, ceramic and fireproof material, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive, filter material and other industries.

Admiral quartz have higher fireproof performance, industrial quartz sand is often divided into: ordinary quartz sand, fine quartz sand, high purity quartz sand, fused quartz and silicon powder, etc.

Ordinary quartz sand

Ordinary quartz sand, namely SiO2 90-99% Fe2O3 0.06 or less - 0.02% or higher, refractoriness 1750 ℃, the exterior part of the larger particles, the surface has a yellow skin cyst. Ordinary quartz sand is usually is made of natural quartz ore, after crushing, washing, drying, secondary screening and become a kind of water treatment filter material; The filter material has: no impurities, no edges, density, mechanical strength, high load carrying capacity line long use cycle characteristics, is the ideal material of chemical water treatment. Particle size range 5-220 mesh, grain production according to user requirement. Main application: metallurgy, silicon carbide, glass and glassware, enamel, cast steel, water filtration, paohuajian, chemical industry, spray noisy and other industries.

The refined quartz sand

Fine quartz sand

Fine quartz sand

Also called pickling quartz sand, SiO2 acuity 99-99.5% Fe2O3 0.005% or less, is made of high quality natural quartz sand, cement mortar
