NaAlSi3O8

Albite (sodium aluminosilicate) is a feldspar ceramic mineral and the sodium end-member of the plagioclase feldspar solid-solution series. It is a naturally occurring compound that serves as a primary constituent in many engineered ceramics, glass-ceramics, and porcelain formulations. Albite is valued in industrial ceramics for its role in lowering firing temperatures, improving vitrification, and enhancing mechanical strength; it is widely used in whitewares, sanitary ceramics, and architectural tiles where compositional control of the feldspar phase enables tailoring of thermal expansion and densification behavior. The material is also significant in refractory compositions, glass manufacture, and as a model compound in materials research on ceramic phase equilibria and sintering mechanisms.
