Feldspar powder constitutes an aluminosilicate mineral comprising potassium, sodium, calcium, barium, and other alkali metals or alkaline earth metals. Its key constituents include SiO2, Al2O3, K2O, Na2O, CaO, among others.
Playing crucial roles in clay bodies and glazes, feldspars serve primarily as fluxes in formulations, while also contributing additional alumina and silica. These naturally occurring minerals are typically categorized as either potash or soda feldspars, depending on the predominant alkali metal element present.
Feldspar serves as the primary raw material for a diverse range of ceramics, mitigating drying shrinkage and body deformation while enhancing drying efficiency and reducing drying time.
In the realm of glass production, it acts as a crucial ingredient in flat glass and various glass products, effectively lowering the melting temperature of glass compositions.
Furthermore, feldspar finds utility across multiple industries, serving as a raw material for papermaking, coatings, welding rods, and other fillers. It also features prominently in abrasive abrasives and as a component of refractory materials.
