PHENOMENA AND PROCESSES OF THE SYNTHESIS OF NEW GLASSY AND NANO-STRUCTURED GLASS-CERAMICS MATERIALS

The subject of this project is the study of phenomena and processes during the synthesis of: - Nano-structured glass-ceramics materials. The determination of the composition range over which nano-crystallization occurs is planned. The influence of different types of cations and anions, their contents, mixed alkali effect, conditions of heat treatment (temperature, time) etc., on nucleation and growth of nanocrystals will be studied. - Multi-component phosphate and invert phosphate glasses and glass-ceramics. ?h? investigation of the influence of different types of cations during the replacement of phosphorous and of the conditions (temperature, time) on phenomena and processes in complex compositions. - Mixed anions silicate glasses and glass- ceramics. The investigations deal with the influence of the type and quantity of the anions which replace oxygen in oxide glasses and cations of transition elements on the phenomena and processes in multi-component glasses. - Coatings based on glassy, glass-ceramics and ceramics powders. The investigations are focused on: Selection of components and substrates, the definition of parameters for powder deposition at selected substrates and the study of the processes occurring during thermal treatments. The expected result of this investigation is the obtainment of new knowledge concerning the phenomena and processes that enable the development of new glassy and glass-ceramics materials applicable for new technologies.
