High Purity Silica Quartz Sand Price 180 Mesh SiO2 98.0-99.20% Low Price

The unique physical and chemical properties of quartz sand play a very important role in today's rapid development of aviation, aerospace, electronics, machinery and information technology industries, especially the internal structure, shape change and lattice of molecular chains, which have high temperature resistance, low Thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties play an increasingly important role in many high-tech products.

Quartz sand is an important industrial mineral raw material, non-hazardous chemicals, widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. Automobile, train transportation, water transportation. Industrial production is generally packaged in 50KG or 25KG, and the export ton packaging specification: 0.5-1.0mm 0.6-1.2mm. 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm mm unit) Ordinary quartz sand.
