Quartz sand 16-800 (mesh), Brand Name : qingyun

Quartz sand profile
quartz sand is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is sio2, quartz sand color for the milky white or colorless translucent, white crystals, multi type globular 7 hardness, brittle no cleavage, conchoidal fracture, oily luster, density 2.65, bulk density (1-20 mesh is 1.6), 20-200 mesh is 1.5, the chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in koh solution, melting point 1750 �.without impurities, high mechanical strength, stable chemical performance, large carrying capacity, long cycle life, good economic benefit.
