What Is the Chemical Formula for Zeolite?

The general chemical formula for zeolite minerals is Mx/n[(AlO2)x(SiO2)y].mH2O, where M is the ion balancing the charge of the aluminosilicate ion Al12Si12O48^12+, which is a component of zeolite minerals. Since the term "zeolite" refers to the aluminosilicate range of minerals, many different chemical formulas can describe different types of zeolite.

One possible chemical formula for a zeolite is Na2Al2Si3O10·2H2O, which is the formula for the zeolite called natrolite. Analcime, another common zeolite mineral, is referenced by the chemical formula NaAlSi2O6·H2O. Chabazite has a chemical formula of Ca2Al4Si8O24.13H2O. Certain cations that are commonly found in zeolites include Na+, K+, Ca2+ and Mg2+.
