Thermal Properties Studied on As2Se3 Model Glass
Non-crystalline materials, which include some inorganic and organic glasses, are characterized by lack of long range order. This fact is responsible for lots of physical and chemical properties, which opens broad possibility for technical applications. Glasses show glass transition, relaxation effects and crystallization under heat treatment with very similar phenomenological peculiarities. Attention has been paid to effects called physical aging. The study of molecular reorganization during aging has not only fundamental scientific importance but it can have an impact on possible technological advances in material science and engineering.
