Thermal stationarity criteria for a proper study on growth (dissolution) kinetics in systems with small volumes of solutions in melts

摘要

It is shown that an application of theories developed on the assumption of the stationary thermal conditions for discussing the results on kinetic experiments with small volumes of solutions in melts is incorrect if the strong measures on eliminating temperature oscillations in these experiments are not taken. The results on an analysis of the influence of various temperature changes on the velocity of migration of liquid interlayers through a crystalline wafer are presented and discussed. Criteria for thermally stationary conditions in kinetic experiments are deduced.
