As the core raw material of silicon raw materials, silica plays an irreplaceable and important role in the production and supply of silicon raw materials. Its unique physical and chemical properties make it play an important role in aviation, aerospace, electronics, machinery and today's fast-growing IT industry, especially its intrinsic molecular chain structure, crystal shape and lattice change. Its high temperature resistance, small coefficient of thermal expansion, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties make it play an increasingly important role in many high-tech products, such as IT. The core technology products of the industry - computer chips, optical fibers, resonators in the electronics industry, new electric light sources, high-insulation sealing materials, aerospace instruments, military technology products, special optical glass, chemical analysis instruments, etc. Do not open these basic materials.

Brief introduction of properties and application of silica sand
Silica sand for foundry is refractory particles with quartz as the main mineral component and particle size of 0.020mm-3.350mm. It is not artificial silica sand and washed silica sand, scrub sand, and selected (flotation) sand according to different mining and processing methods. Silica sand.
