howhow feldspar is used

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.

Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar include pyrophyllite, clays, talc, and feldspar-silica (quartz) mixtures. The abundance of feldspar will make these substitutions unnecessary for the foreseeable future. Uses

Feldspars also are used as fillers and extenders in applications such as paints, plastics and rubber. Beneficial properties of feldspars include good dispensability, high chemical inertness, stable pH, high resistance to abrasion, low viscosity at high filler loading, interesting refractive index and …

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline (KAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).
