Ceramic with feldspar

Feldspar [1] (KAlSi3O8) often said orthoclase, is monoclinic, usually in red meat, white or gray. Density 2.54-2.57g / cm, specific gravity 2.56 ~ 2.59g / cm3, hardness 6, the theoretical component of SiO2 64.7% Al2O3 18.4%, K2O 16.9%. It has a low melting point (1150 ± 20 ℃), melted a long time interval, the melt viscosity characteristics, widely used in ceramic blank, ceramic glazes, glass, porcelain, abrasive materials and other industrial sectors and manufacturing potash use. In addition to being feldspar, there are two polymorphs as variant: sanidine and potassium feldspar. The former Yi Shu monoclinic, also known as feldspar; the latter is the case triclinic. Feldspar glass industry as a raw material in addition to outside (50-60% of the total amount), in the ceramic industry accounts for 30 percent, and the rest for chemicals, glass flux, ceramic body ingredients, ceramic glaze, enamel raw materials , abrasives, fiberglass, welding and other industries. Mainly used in glass, ceramics, can be used for making fertilizer, better quality of K-feldspar for glass and other manufacturing television imaging. Feldspar: K2O.Al2O3.6SiO2, where K2O 9.55%, more than Al2O3 16%, SiO2 70%, the density of 2.56g / cm 3, Mohs hardness of 6, monoclinic, the color is white, red, white, Melting point 1290.
