About Feldspar
The term feldspar refers to a group of alumino-silicate minerals which make up over half of the earth’s crust.
Valued for their high alumina and alkali content, Rawlynx feldspars are used across a range of industrial applications including:
- Ceramics: as a fluxing agent to lower firing temperatures, bond together system components and increase casting rates
- Glass: as a fluxing agent to reduce the melting temperature of quartz and to control the viscosity of the glass
- Coatings & Polymers: as a functional filler and extender with a relatively high Mohs harness (6), low electrical conductivity, good dispersibility and chemical inertness.
