Product Description

High purity quartz sand
Product Name: High purity quartz sand
Purity: 5N(99.999%)
Description: High purity quartz sand is made of natural quartz by special process of crash, sorting and purification.

Packing:25kg/drum;25kg/bag or as customer requirement.

Application: With unique physical and chemical characteristics, high purity quartz sand is widely and importantly used in optics, aviation, electronics, chemical industry, machinery and the rapid development of IT industry. Especially its special internal molecular structures, crystal shapes and the change rules of lattice make it has features of high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and special optical property, which play more and more important parts in high-tech products.
