Feldspars

The chemical composition of feldspars includes alcalic metals, aluminum, silica and oxygen. The general chemical formula is a bit complicated (K,Na) 1-x (Ca,Ba) x (Si 3-x Al 1+x O 8).This complexity is caused by presence of both monovalent and divalent cations which require more complicated heterovalent substitution.
