Feldspar is an aluminosilicate rock-forming mineral containing calcium, sodium and potassium, and its main chemical components are SiO2, Al2O3, K2O, Fe2O3, Na2O and CaO. There are many kinds of it, such as potassium feldspar, albite, calcium feldspar, barium feldspar, barium ice feldspar, microcline, orthoclase, sanidine and so on. All have a glass luster and a variety of colors. Some transparent, some translucent. Feldspar itself should be colorless and transparent, and some feldspar is colored or not completely transparent because it contains other impurities.
Glass industry: feldspar is an important component of glass manufacturing and an important raw material because it acts as a flux, reduces the melting temperature of quartz and helps control the viscosity of glass. The alkali content in feldspar acts as a flux and reduces the melting temperature of the glass compound, thus reducing the production cost.
Ceramic industry: feldspar plays the role of barren raw materials in ceramic body ingredients, reducing the drying shrinkage and deformation of the body, improving the drying performance and shortening the drying time. During firing, feldspar as a flux can reduce the firing temperature, promote the melting of quartz and kaolin, accelerate the formation of mullite, and improve the density and mechanical strength of the body.
Enamel frits and glazes: Feldspar helps to enamel the composition, ensuring that the final product is flawless and neat
Abrasive industry: The particle size of feldspar can be used as an abrasive, such as a component of ceramic cement, for making grinding wheels.
Construction industry: broken feldspar can be used as a raw material for concrete or plaster for building walls, floors and roofs. Feldspar can also be used for road paving and dam construction.
In the chemical industry, feldspar's rich aluminum and silicon elements can be used to manufacture paint, coatings, fertilizers, rubber and other chemical products; Potash feldspar can also be used as a raw material to extract potash fertilizer.
