Feldspar

Feldspar powderFeldspar is the most abundant matter in the earth’s crust which forms about 60% of terrestrial rocks. It is the most essential component in igneous, metamorphic and sedimentary rocks. Feldspar is generally crystallize from magma in various forms like sodium feldspar, potassium feldspar and mixed feldspar. So Feldspar is basically a group of rocks forming tectosilicate minerals with chemical formula (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) The alkali and alumina contents in feldspar makes it very important component to be used for industrial purposes. Sodium, potassium and mixed feldspar can be distinguished depending on the alkali content they have. It plays a very important role as fluxing agents in ceramic and glass industries and also as functional fillers in paint, plastic, rubber and adhesive industries. Most of the daily used products made with feldspar are fibreglass for insulation, glass for protection, glass for drinking purposes, the flooring and shower basins in our bathroom and tableware where we eat. So it is an important component of our daily life.
