Feldspar

Most of the products we use every day are made with feldspar, the most abundant group of minerals in the earth’s crust. Feldspars have both alkali and alumina content which makes them particularly valuable in industrial processes.

Feldspar alumino-silicates act as a flux to lower the temperature of vitrification and provide alumina which promotes hardness, durability and resistance to chemical corrosion in ceramic wares, electrical porcelain, and all types of glass and fiber insulation.

Feldspars play an important role as fluxing agents in ceramics and glass production, and are also used as functional fillers in the paint, plastic, rubber and adhesive industries.
