Ultra high purity quartz sandUltra high purity quartz sand

Product Details

Ultra-high purity quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless and translucent, with a hardness of 7, which is brittle and unsolvable. Physics, shell-like fracture, grease luster, density of 2.65, bulk density (1-20 mesh is 1.6~1.8), 20-200 mesh is 1.5, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid , Slightly soluble in KOH solution, melting point 1750℃.

Common specifications are: 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.

Quartz sand is a colorless, transparent variant of quartz. The Greeks called it "Krystallos", meaning "white ice". They believed that quartz was durable and strong ice. Ancient Chinese believed that cold crystals in the mouth could quench thirst. Quartz sandstone is a consolidated clastic rock with a content of more than 95% of quartz clastics. It comes from a variety of magmatic rocks, sedimentary rocks and metamorphic rocks. There are few heavy minerals. The associated minerals are feldspar, mica and clay minerals. Quartzite is divided into two types: sedimentary genesis and metamorphic genesis. The former has no obvious boundary between clastic particles and cements, and the latter refers to quartzite ore with deep metamorphism and pure quality. Vein quartz is formed by the action of hydrothermal, almost entirely composed of quartz, with a dense block structure. The mineral content in quartz sand varies greatly, with quartz as the main component, followed by feldspar, mica, cuttings, heavy minerals, and clay minerals.
