Formation of polyantimonic acid and alpha-zirconium phosphate in perfluoroionomer membrane

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