Abstract

The results of microscopic and X-ray studies of polymorphic transformations II ↔ I in K0.945Rb0.055NO3 are discussed. It is shown that the transformations II ↔ I in the studied crystal are enantiotropic in nature and occur with the formation and growth of nuclei of the daughter modification inside the matrix. The equilibrium temperature between the II and I modifications is Т0 = 455 ± 0.5 K. It is determined that in K0.945Rb0.055NO3 the transformation II ↔ I is of a single crystal–single crystal nature.
