KINETICS OF GAS-SOLID REACTIONS IN ALPHA-ZIRCONIUM PHOSPHATE - H+-NA+ MIXED DIFFUSION-COEFFICIENTS Academic Article

abstract

• The rates of reaction between gaseous HCl and sodium ion exchanged phases of -zirconium phosphate have been measured. The reactions are diffusion controlled and were fit by an equation for diffusion in a sphere from a well stirred fluid of limited volume (Carman and Haul equation). Diffusion coefficients were of the order of 10-15-10-12 cm2/sec in the temperature range 25-220C. These coefficients are in the same range as those determined from self-diffusion studies but are several orders of magnitude smaller than those obtained from rates of exchange. Possible reasons for this discrepency are given. 1981.
