Introduction and Application of Quartz and Quartz Powder in Yuanlei Small Classroom

 

Quartz is the mainrock-forming mineralOne, generally refers to low-temperature quartz (α-quartz), yesquartz group mineralOne of the most widely distributed minerals. Generalized quartz also includes high-temperature quartz (Beta-quartz) and coequartz, etc.

 

 

       Quartz is a mineral composed of silica,Chemical formulaSiO2. Pure quartz colorless transparent, the Greeks called“Crystal”, which meansWhite ice.They are convinced that quartz is durable and strong ice. Ancient Chinese believed that cold crystals in their mouths could quench thirst. Due to trace pigment ions or fine dispersioninclusions, or there is a color center and a variety of colors, and reduce transparency. It has glass luster, and the fracture is grease luster. Hardness7, no cleavage, shell-shaped fracture. Specific Gravity2.65.Toolspiezoelectricity.

 

 

 

Quartz powder (the same as quartz sand) is also calledsilicon powder. Quartz powder is a hard, wear-resistant, chemically stablesilicate mineralIts main mineral composition isSiO2 Bulk density(20-200The purpose is1.5)Its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble inKOHsolution, melting point1750 ℃.

 

 

extracted from the mineQuartz StoneAfter processing, the general fineness in120(less120mesh) of the product is called quartz sand. More120The purpose product is called quartz powder.

 

 

Use:Manufacture of glass, refractory materials(furnace charge), smelting ferrosilicon, coatings, rubber filler,metallurgical fluxceramics,abrasive material, metal surface treatment and other aspects, in the construction of its use has a strong resistance to acid medium erosion capacity, the productionacid-proof concreteAnd acid resistant mortar.

Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.
