| Abstract;Molecular compounds can be obtained in principle as crystalline as well as vitreous states. The latter state has been prepared traditionally by a rapid cooling of their liquids. This method is not a univeral way for the molecular system that undergo thermal decomposition on heating. Milling of molecular crystals was found to be alternative safe way in realizing their vitreous states. The glass transition, crystallization and fusion were generally observed. Some compounds can be vitrified in single system, and some in binary system. Formation of solid solutions in molecular crystals in severely constrained by many structural factors, but many binary molecular systems are formed under nonequilibrium condition in their partial or full concentration range. This solid-state vitrifi-cation is not only intriguing from basic viewpoints concerning the state of aggregation of molecules but also will find some industrial applications. (author abst.) |
