Feldspar is primarily used in industrial applications for its alumina and alkali content. Feldspar is a naturally occurring anhydrous, inorganic, igneous rock. The fusibility of the mineral makes it useful raw material for manyapplications and the purity is the indication of better fusibility in the application. There are two types of it depending On Na2O and K2O SODA FELDSPAR POTASH FELDSPAR CERAMICS ENAMEL FRITZ & GLAZED INSULATORS GLASS MILD ABRASIVES PICTURE TUBES SANITARYWARE TABLEWARE VITRIFIED TILES WELDING ELECTRODE Custom sizes and Material of required specifications can be made in case of Bulk and Regular orders.
