Nepheline Syenite
Na₃KAl₄Si₄O₁₆
Low-silica feldspathoid flux mineral supplied for ceramics, glass, and glaze applications requiring low-temperature vitrification.
Overview
Nepheline syenite offers higher alumina and alkali flux with lower silica than conventional feldspar, enabling reduced firing temperatures and improved vitrification in ceramic bodies and glazes. It is commercially valued for energy efficiency, enhanced whiteness, and fired surface quality in tiles, tableware, and glass batches.
