Faujasite-Mg

Faujasite (FAU-type zeolite) is a mineral group in the zeolite family of silicate minerals. The group consists of faujasite-Na, faujasite-Mg and faujasite-Ca. They all share the same basic formula (Na2,Ca,Mg)3.5[Al7Si17O48]·32(H2O) by varying the amounts of sodium, magnesium and calcium. Faujasite occurs as a rare mineral in several locations worldwide. Faujasite materials are widely synthesized industrially. The relatively low-silica (Si/Al<2) synthetic faujasite is called Zeolite X and the high-silica (Si/Al>2) one is called Zeolite Y.
