Feldspar is an excellent source of alumina which improves end product hardness, durability, and resistance to chemical corrosion. Used in ceramics, feldspar and pegmatite are the main vitrifying or fluxing agents used during the firing process of ceramic bodies. Fluxes melt at an early stage in the firing process forming a glassy matrix that ...

Feldspars are important ingredients in clay bodies and glazes. In both applications, their primary function is to supply fluxes to the formulations, but they also provide additional alumina (Al2O3) and silica (SiO2). Feldspars are naturally occurring minerals and are generally classified as either potash (potassium) or soda (sodium) …
