2006-11-1 · Feldspar is extensively used in various industrial applications such as glass and ceramics due to its alumina and alkali contents. The mineralogical composition of most feldspar minerals can be expressed in terms of the ternary system: orthoclase (KAlSi 3 O 8), albite (NaAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).
