  • THE FELDSPAR GROUP OF MINERALS

    The potassium or K-feldspars are polymorphs, meaning they have the same chemistry, KAlSi 3 O 8 , but different structures and therefore are different minerals. The plagioclase feldspars are a set of minerals that are in a series from a sodium rich end member, albite, to a potassium rich end member, anorthite.

  • Feldspar Statistics and Information | U.S. Geological Survey

    Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.
