Quartz sand is divided into two types, refined and common: the hardness of quartz is 7, the specific gravity is 2.65, the color is milky white, light yellow, brown and gray. Quartz has high refractory performance. Fluxes, ceramics, abrasive materials, casting, use of quartz’s strong resistance to acid medium erosion in construction, used to make acid-resistant concrete and acid-resistant mortar. Especially used as water treatment filter material, high strength, strong interception ability, good acid resistance. It is also the main raw material for industries such as glass, ceramics, enamel, thermo bottles, sodium silicate, casting, building materials, grinding, refractory, military industry, and communications.
