abstract

  • The dehydration characteristics of two sodium ion exchanged phases of crystalline -zirconium phosphate have been determined. The half-exchanged phase, Zr(NaPO4(HPO4 5H2O, was found to form two lower hydrates and an anhydrous phase. At a temperature of 390 or higher sodium or dizirconium triphosphate, NaZr2(PO4)3, was obtained. The fully exchanged phae, Zr(NaPO4)2 3H2O, forms one lower hydrate and three anhydrous phases. The sodium ion may be eluted from all of these phases to recover the original -zirconium phosphate crystals except for the fully exchanged phase heated to 800C which yields a new form of zirconium phosphate. 1970.
