Sodium feldspar

Sodium Feldspar :

Soda-feldspar as known as Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. As such it represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi3O8. Soda Feldspar is generally a clean white m ineral that sources sodium, alumina and silica along with some potassium and calcium.


The salient features of our product are
  • High alkali content and balanced chemistry speed up the transition rate of glass phase in vitrified tiles.
  • Improve the maturity at desired temperature and also imparts better compactness.
  • Homogeneous particle size distribution exhibits better thermal properties.
  • Stabilize the firing temperature with broad thermal range.
  • Contribute good whiteness and glossiness.
