Nepheline Syenite

Nepheline Syenite

Nepheline syenite provides geological clues to environment of formation. It is a quartz-free aluminium silicate consisting primarily of the minerals nepheline, microcline and albite. Because of its extremely low melting point and high alumina content, it is processes for energy savings, and can be further modified to produce functional fillers for paint, powder coatings and plastics. The industrial use of nepheline syenite includes refractories, glass making, ceramics and, in pigments and fillers.
