About Nepheline syenite
Learn more about how Rawlynx's nepheline syenite helps glass manufacturers to reduce energy consumption.
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, Rawlynx nepheline syenite is used as a flux in ceramics, to lower melting temperatures in glass, and as a functional filler in coatings and polymers.
Mined and processed at our premium deposit in Stjernøy, Norway, our nepheline syenite products are characterised by:
- high purity
- low melting point
- high alumina content
