Quartz sand Industrial Grade in bags

Quartz sand 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, hardness of 7, quartz sand is important industrial mineral raw material, the hazardous chemicals, widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.

Basic introduction to the editor

Quartz sand is the quartz writing processing of silica particles. Also known as silica, quartz, quartz rock) is a texture hard, wear-resisting, stable chemical properties of silicate minerals. In nature exist in quartz sandstone, quartzite and vein quartz. Quartz sandstone is consolidation of clastic rocks, quartz particles content more than 95%,

The refined quartz sand

The refined quartz sand

From all kinds of magmatic rocks, sedimentary rocks and metamorphic rocks, heavy minerals is less, associated minerals as feldspar, mica and clay minerals content. Quartzite sedimentary origin and metamorphism, the boundaries of the former clastic particles and cement is not obvious, which is a deep metamorphic grade, quality, and the pure quartz ore. Vein quartz is formed by hydrothermal process, almost all is composed of quartz, dense block structure.

Quartz sand mineral content change is bigger, give priority to with quartz, followed by feldspar, mica, cuttings, heavy mineral, clay minerals content, etc.

Quartz sand 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, 7 hardness, brittle no cleavage, conchoidal fracture, oily luster, density 2.65, bulk density (1-20 mesh is 1.6), 20-200 mesh is 1.5, the chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃.

Quartz sand commonly used specifications are: 0.5 1 mm, 1 -- 2 mm, 2 -- 4 mm, 4-8 mm, 8 -, 16-32 mm, 16 mm 10-20 yard, 20 to 40, 40-80 mesh, 100-120 mesh
