GRAIN GROWTH IN LABORATORY PREPARED ICE : SOLUTE EFFECTS

Abstract
Grain growth experiments were carried out using cylindrical ice samples grown from pure water and from water solutions of NaCl, NH4OH and HF. Solute concentrations were varied from 10-1 M to 10-4 M and annealing was performed within the range -2°C to -16°C. The results obtained show that the grain growth rate is increased when solutes are added to ice. This behaviour may be related to changes in grain boundary structure and mobility
