As a mineral, feldspar is categorized primarily as albite, microcline, orthoclase, and amortize. The kind of alkali they contain can help to further distinguish between sodium, potassium, and mixed feldspars. In addition to being utilized as a functional filler and extender in the paint, plastics, rubber, and adhesive industries, feldspar is a common mineral raw material used as a fluxing agent in the manufacture of ceramics and glass. Feldspars have a number of benefits, including their dispensability, chemical inertness, constant pH, good resistance to abrasion, low viscosity at high filler loading, interesting refractive index, and resistance to icing.
