Nepheline syenite
Nepheline syenite is a quartz-free aluminium silicate. It primarily comprises nepheline, microcline and albite. Because of its extremely low melting point and high alumina content, Sibelco nepheline syenite is used as a flux in ceramics, to lower melting temperatures in glass, and as a functional filler in coatings and polymers.
