Zeolites can be categorized in relation to the Si/Al ratio, i.e. low silica zeolites (Si/Al mole ratio = 1–2 , SiO2/Al2O3 mass ratio = 1.18–2.35), medium silica zeolites (Si/Al mole ratio = 3–10).
Madhukar Baburao Deshmukh, if a compound with elemental analysis as follow; Si = 25 %, Al = 12.5 %, and Na = 11 %. It is possibly zeolite! How to detect its type ?
