This mineral is often called potassium feldspar or K-feldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 …

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.
