Nepheline Syenite

Nepheline syenite is a quartz-free aluminium silicate consisting primarily of the minerals nepheline, microcline and albite.

Because of its extremely low melting point and the high alumina content, nepheline syenite is used as a glass phase promoter, a ceramic flux and also as a functional filler in paint, plastics etc.
