Abstract
Growth and dissolution of crystals in Sr(NO_3)_2-H_2O system which has a peritectic temperature T_p=29℃. Both high- (Sr(NO_3)_2) and low- (Sr(NO_3)_2・4H_2O) temperature phases can grow simultaneously in a liquid of the composition near the peritectic point when the liquid is cooled below T_p. The latter phase begins to melt congruently at a temperature above T_p, which is followed by the formation of the latter phase in the produced liquid.
