Products: Potassim Feldspar

We provide potassium feldspar, which is used widely in the ceramics. Potassium feldspar is available in two major categories such as plagioclase feldspar and alkali feldspar (most of which are potassium feldspar or K-feldspar). Potassium feldspar is based on silica group. It is ideal to be used as bonding agent with magnesium oxide, magnesium chloride and other synthetic glue for production of abrasives, wheels, discs and other shapes.
