High SiO2 content quartz stone, with fewer impurities. Quartz sand characteristics: quartz hardness is 7, specific gravity 2.65, color ranges from milky white, pale yellow, brown to gray. Quartz has high refractoriness, with a melting point of 1730 degrees Celsius. Mainly used for processing quartz sand and quartz powder.
Quartz powder is produced by crushing and screening quartz ore. Quartz sand (powder) is primarily used as a key raw material in industries such as glass, ceramics, enamelware, thermos bottles, sodium silicate, casting, building materials, grinding, refractory materials, water filtration, military, and communication.
Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral, primarily composed of SiO2. It has a milky white or colorless, translucent appearance, with a hardness of 7, brittle without cleavage,贝壳状 fracture, and an oily luster. Its relative density is 2.65, and it exhibits significant anisotropy in its chemical, thermal, and mechanical properties. It is insoluble in acids, slightly soluble in KOH solution, and has a melting point of 1750°C. The color ranges from milky white, pale yellow, brown, to gray. Quartz has high耐火 performance.
The unique physical and chemical properties of quartz sand place it in a crucial role in the aviation, aerospace, electronics, mechanical, and rapidly evolving IT industries. Its inherent molecular chain structure, crystal shape, and lattice transformation patterns confer it with high-temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect, and distinctive optical properties, which play an increasingly significant role in many high-tech products.
Product Applications:
Manufacture glass, refractory materials, smelting silicon iron, metallurgical fluxes, ceramics, abrasive materials, casting. Quartz, with its strong resistance to acidic medium erosion, is utilized in construction for producing acid-resistant concrete and mortar. Quartz sand, as the core raw material for silicon, plays an indispensable foundational role in the production and supply of silicon raw materials.
