Bivariant (High- And Low Temperature) Crystallization Of Some Simple Glassforming Substances, And Polymorphous-Crystalloid Structure Of Glass

According to the Concept of Polymeric Polymorphous-Crystalloid Glass Structure (CPPCGS), which has been developed for the last decade, bi-variant crystallization is inherent in glass-formers constructed of enantiotropically inter-transforming fragments of structure of high and low temperature polymorphous modifications (HTPM and LTPM), which have no long range order (crystalloids). In glass formers characterized by mono-tropic transformation, the only process is possible which results in mono-variant crystallization.
