Potash Feldspar- Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar. Feldspars are primarily used in industrial applications for their alumina and alkali content. The term feldspar encompasses a whole range of materials. 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. Applications of Feldspar: Glass: Feldspar is an important raw material, because the alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs. Ceramics: Feldspars are used as fluxing agents to form a glassy phase at low temperatures and as a source of alkalis and alumina in glazes. Fillers: Feldspars also are used as fillers and extenders in applications such as paints, plastics and rubber. Enamel frits and glazes: Feldspar assists the enamel composition, assuring the absence of defects and the neatness of the end product: e.g. enamel frits, ceramic glazes, ceramic tile glazes, sanitary ware, tableware, electrical porcelain and giftware. And many other end-uses: paint, mild abrasives, urethane, welding electrodes (production of steel), latex foam, the welding of rod coating, and road aggregate. We produce POTASH FELDSPAR (K-SPAR) in forms of: Granular Particles Powder (150-25 microns) Lumps form 1 inches to 15 inches
