"The aim of the project is the preparation of new phosphate and borophosphate based glasses modified by addition of metal oxides improving glass forming ability, chemical durability, thermal stability and other properties. The modification of the glass composition will be done by the additions of higher-valent oxides (In2O3, TeO2, GeO2, MoO3, WO3). The main target of the project is the investigation of their structure using Raman, IR and NMR spectroscopy and the study of the relations between composition, structure and properties of glasses. The glass forming ability will be ascertained and glasses will be prepared and characterized by the measurement of their basic properties. Also their thermal behaviour (including study of nucleation rate, crystallization mechanism and kinetics) will be studied. Glasses with divalent oxides (ZnO, PbO, MgO) and also univalent oxides (Li2O, Ag2O) will be prepared. At silver- and lithium-containing glasses their electrical properties will be studied as well for their application in electrotechnics."@en . . . "2013-02-01+01:00"^^ .
