Quartz glass is a kind of glass containing only silicon dioxide. Because of different types, processing techniques, and raw materials, they are often called silicate glass, quartz glass, fused quartz, fused quartz, and fused quartz, as well as transparent, translucent, and opaque quartz that have not been defined overseas. In China, quartz glass is commonly called quartz glass, which is classified according to the processing method, main use and appearance, such as transparent quartz glass for electric melting pipe fittings, continuous melting quartz glass, gas refining transparent quartz glass, generated quartz glass, opaque quartz glass, electronic optical quartz glass, quartz glass for semiconductor materials, and quartz glass for energy-saving lamps.

In the production of refined quartz sand, generally speaking, there are three ways of iron removal: mechanical equipment wiping iron removal, magnetic separation equipment iron removal and ultrasonic wave iron removal. The iron removal by mechanical equipment wiping is mainly to remove the iron residue outside the quartz sand raw ore according to the effect of external force. There are two kinds of mechanical equipment wiping: rod mill wiping and mechanical equipment wiping. When using mechanical equipment to remove iron, some aqueous solutions are also required to cooperate with each other, and the concentration value of coal slurry is set to a certain ratio to remove iron from raw ore quartz sand. However, this kind of iron removal method is only applicable to some manufacturers with small production capacity or the situation where the quality of raw quartz sand is very good.

As the key raw material of silicon raw material, quartz sand plays an irreplaceable role in the production, manufacture and supply of silicon raw material. Fine quartz sand can be used as wear-resistant material for grinding glass, etc. Quartz sand is a very stable silicate mineral, which ensures that it is not easy to damage the production process by chemical reaction with other raw materials during glass production. Secondly, quartz sand has high strength and hardness of 7, which increases the firmness of glass and makes glass, glass instruments and equipment more firm; The quartz sand is mostly milky white and translucent, which gives a very convenient standard for the production of various colored plates and colorless glass.

The scratch hardness of quartz sand filter material is also called Mohs hardness tester. Mainly used for hardness and softness of different minerals. The method is to first select a component with one hard end and one soft end, then cross the tested material along the component, and determine the hardness and flexibility of the tested material according to the length of the scratch. In terms of quality, hard objects have long scratches and soft objects have short scratches. Hardness of quartz sand filter material. Mainly used in metal materials and quartz sand materials. The method is to put the tension of the specification into the tested material at the load effect, and compare the hardness and softness of the tested material with the partial plastic deformation of the material surface.

Quartz sand filter material can often distinguish ordinary quartz sand from refined quartz sand, first because its appearance is very different. The second is the manufacturing process. Generally, quartz sand for sewage treatment only needs simple processing processes such as crushing and drying. The raw quartz sand used for general quartz sand is also different from refined quartz sand. The surface layer is generally yellow skinned quartz sand. The iron ore without impurities on the surface layer is immediately produced and processed into refined quartz sand, but the quality of iron ore is poor. After acid pickling and passivation of refined quartz sand, its pale yellow surface is melted and cleaned after acid pickling and passivation, and its appearance is transparent, beautiful and generous.
