    Aug 10 2019 · 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 C respectively.

    Feldspars of importance to ceramics are aluminosilicates of sodium potassium and calcium (Jones Berard 1993) They are used as fluxes to form a glassy phase in bodies thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8) orthoclase or microcline (KAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).
