A.Technological Characteristics

Determine the process characteristics of the silica, the value of industrial applications is: silica, hard texture, Mohs hardness of 6, excellent fire resistance and acid resistance, melting point 1730 ° C, the melt cooled into a quartz glass, crystal crystal, with a thorough over ultraviolet light and piezoelectric.

Two. The main purpose

1) the metallurgical industry: mainly used in the manufacture of refractory materials - brick, smelting silicon alloys (ferrosilicon, silico-manganese, silicon, chromium), and for the flux. Quality can be prepared pure crystalline silicon. Crystalline silicon is the main raw material for the production of silicon, but also system Silica-alumina and silicone.2) the glass industry: silica is the main raw material for making glass. Silica can be used as ordinary optical glass, pure quality may be melting into a high-quality technical glass. Refractory bricks for the kiln lining of glass furnaces.3) Construction Industry: can be used as an important building block. Gravel for road filled with stone and railway ballast. Sand mixed with asphalt paving, quartz calibration materials can be made of Portland cement.4) Chemical industry: silica can produce a variety of silicides and silicates, and nitrates, good quality and those who can be used for the filling in the acid resistance of the sulfuric acid tower.5) the abrasives industry: quartzite and quartz sandstone can be made to the grindstone, whetstone, and sandpaper, and carbonated silicon abrasive material; quartz sand are mostly used to cut stone, polished glass, grinding the surface of metal products and stone products, quartz is also used to The pondering jewelry.6) other industries: for enamel and ceramic materials. Pure quality, widely used in the radio industry, ultrasonic technology and modern national defense and state-of-the-art technology, pure quartzite with optical and ultraviolet radiation can produce a variety of optical instruments and medical quartz lamp, and also the manufacture of silicon carbide (carbide the basic raw material of silicon). Fine quartz sand can be used for filtration.Quality specifications:(1) 9-11cm of products accounted for 90%, other 10% of the product specifications for the 5-13cm.(2) roundness. Silicon content of 99.8%(3)   of the surface mud and other impurities
