Abstract: Inorganic ion exchanger, viz., polyantimonic acid (PAM) and α-zirconium phosphate (ZrP) were synthesized vitreously using a novel approach involving solvent media instead of conventional aqueous media. The exchangers were also incorporated into a perfluoro ionomer membrane matrix employing the solution systems used in vitreous preparations. The spectra of vitreously synthesized and in situ precipitated exchangers were compared with spectra of those obtained by reported methods. The similarities in spectra of H+ as well as exchanged forms suggest the in situ formation of crystalline PAM and α -ZrP.
