Nepheline Syenite

Mineral: Nepheline Syenite 

 

Nepheline syenite can be characterised by:

 

  • High purity
  • Absence of free crystalline silica (free of labelling)
  • Brightness
  • Relatively low refractive index, making it a transparent filler in various binders
  • High inertness in various media
  • Easy wetting
  • Transparency for UV-radiation (i.e. suitable for UV-curing processes)
