K-feldspar (KAlSi3O8) are commonly called orthoclase belongs to monoclinic system,specific gravity 2.56 ~ 2.59g/cm3, a theoretical composition of SiO2, Al2O3, K2O.
It has a low melting point (1150 ± 20), melting interval for a long time and high melt viscosity, is widely used in ceramic billets, ceramic glazes, glass, and porcelain, grinding materials and other industrial sectors and manufacturing potash fertilizer use.
Feldspar in addition to being outside the glass industrial raw materials (about the total amount of 50-60%), in the ceramic industry in the use accounted for 30% of the remainder used in chemical, glass flux, ceramic green body ingredients, ceramic glaze, enamel raw materials,abrasives, glass fiber, welding and other trades.
Mainly used in glass, ceramics, it can also be used for the system to take potash fertilizer, better quality of K-feldspar glass, etc.
