无臭。无味。热膨胀系数是已知物质中最小的。熔融物呈玻璃状。溶于过量氢氟酸生成四氟化硅气体。能被热的浓磷酸侵蚀。几乎不溶于水或其他酸。无定形粉末能在浓碱溶液中缓慢溶解。能与熔融的碱类起作用,生成可溶性硅酸盐。有刺激性。 The main purpose of ordinary quartz sand for filtration: metallurgy, silicon carbide, glass and glass products, enamel, cast steel, water filtration, soda, chemical, spray and other industries. Refined quartz sand: Si02 ≥ 99 — 99.5% Fe203 ≤ 0.02-0.015%, made of carefully selected high-quality ore for complex processing. The material range is 5-220 mesh, which can be produced according to user requirements, and the appearance is white or crystalline. Main uses: high-grade glass, glass products, refractory materials, smelting stones, precision casting, grinding wheels, etc.
