FELDSPAR
HomeFELDSPAR
Feldspar is an abundant rock-forming mineral which usually ranges from off-white, or pink to pale-coloured. It is known as a natural source of potassium oxide (K2O), Sodium Oxide (Na2O) and Aluminium oxide (Al2O3)
Feldspar comprises a group of minerals containing potassium, sodium, calcium & aluminium silicates. It is a universal flux used in all types of ceramic bodies &glaze. Feldspars are primarily used in industrial application for their alumina & alkli content. We produce both high quality sodium & potassium feldspar as per client requirement . The glass & ceramic industries are the major consumers of feldspar. Available in chips & powder form.
Feldsper lumps/ chips in 2-5 mm and larger sizes :
- Potash Feldsper (Pink) : 12.5%(K2o), 2%(Na2o), 0.15%(Fe2o3)
- Soda Feldspar (White) : 9.5%(K2o), 1.5%(Na2o), 0.15%(Fe2o3)
