Abstract
A new family of crystalline and microporous compositions having indium and silicon as essential framework elements have been synthesized. These compositions are characterized by unique x-ray diffraction patterns and an empirical formula of: EQU A.sub.p (In.sub.1-n M.sub.n).sub.y Si.sub.1-z Ge.sub.z O.sub.x where A is a cation such as sodium or potassium and M is a metal having a valence of +3, +4 or +5 such as iron (+3), titanium (+4) and niobium (+5).
