IONIC DIFFUSION AT THE ICE-SOLID INTERFACE

DIFFUSION OF SODIUM CHLORIDE AT THE ICE-ALUMINUM INTERFACE WAS DETERMINED IN INVESTIGATING THE NATURE OF WATER AT THIS JUNCTION. THE AVERAGE VALUE OF THE DIFFUSION COEFFICIENT OF SODIUM IONS, DETERMINED AT 6 DIFFERENT TIMES RANGING FROM 8 TO 28 DAYS AFTER INTRODUCTION OF THE IONS TO THE INTERFACE IS PRESENTED. COMPARISON OF THESE VALUES WITH THE DIFFUSION COEFFICIENT FOR IONIC DIFFUSION IN BULK LIQUID WATER, AND WITH THAT EXPECTED FOR IONIC DIFFUSION IN ICE, INDICATES THAT THE PROPERTIES OF THE INTERFACE ARE CONSIDERABLY DIFFERENT FROM THOSE OF EITHER BULK LIQUID WATER OR ICE. LACK OF ANY CONSISTENT TIME DEPENDENCE OF THE DIFFUSION COEFFICIENT SUGGESTS THAT THE NATURE OF THE INTERFACE WAS LITTLE DISTURBED BY THE ADDITION OF SODIUM CHLORIDE. THESE OBSERVATIONS SUPPORT THE VIEW THAT A TRANSITION ZONE 5 TO 10 ANGSTROM THICK WITH LIQUID-LIKE PROPERTIES EXISTS AT THIS INTERFACE. A MODEL OF THIS CONCEPT OF THE ICE-SOLID INTERFACE IS PROPOSED. /AUTHOR/
