The term feldspar refers to a group of alumino-silicate (tectosilicates) minerals which make up over half of the earth’s crust. Due to their high alumina and alkali content, 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.

PERO specializes in fine and specificaly selected micronised feldspathics in 2 main groups.
