Ionic conductivity of anhydrous zirconium bis(monohydrogen orthophosphate) and its sodium ion forms Academic Article uri icon

abstract

  • Conductivities have been measured by the vector impedance method for the layered compounds anhydrous α-zirconium phosphate, Zr(HPO4)2, and several of its sodium ion phases. The values of the ionic diffusion coefficients are of the order of 10-6-10-8 cm2/s at 200°C and activation energies range from 15.6 cal/mol for Zr(HPO4)2 to 18.6 cal/mol for ZrHNa(PO4)2. Comparisons are made with literature values of conductivity and self-diffusion coefficients for Zr(NaPO4)2·3H2O and kinetically determined diffusion coefficients for the phases containing both sodium and hydrogen ions. © 1982.
