Feldspar
KAlSi₃O₈ / NaAlSi₃O₈
Feldspathic flux mineral supplied for ceramic bodies, glazes, glass, and industrial mineral blending applications.
Overview
Feldspar is the most widely used fluxing mineral in ceramics and glass, providing alkali contribution and promoting vitrification at ceramic firing temperatures. It is commercially selected by Kâ‚‚O and Naâ‚‚O balance, iron content, and particle size for tile bodies, sanitaryware, tableware, and glass batch applications.
