Feldspar

Feldspar has a wide range of Industrial uses due to the contamination of Alkalis like Oxides of Potassium & Sodium and Alumina. Due to these properties, Feldspar plays vital role as fluxing agent in Glass and Ceramic applications and can be used as filler in rubber, plastic, paint and adhesive industries.
Potassium Feldspar
Most of the products we use on a daily basis are made with feldspar: glass for drinking, glass for protection, fiberglass for insulation, the floor tiles and shower basins in our bathrooms, and the tableware from which we eat. Feldspar is part of our daily life.
