Essay

The Dissertation is devoted to the investigation of physico-chemical particularities microinhomogenical structure of melts and glasses and expansions of views about crystalline phases content and phase transformation in the following systems: PbO-SiO2, PbO-Al2O3-SiO2, PbO-Na2O-SiO2, PbO-CaO-SiO2, PbO-MgO-SiO2. By the complex of physico-chemical methods of analyse using improved a high-temperature isothermal centrifugation (HTIC) of melts of this systems was studied. By means of HTIC of melts, it is possible to obtain gradient glasses. Key words: high-temperature isothermal centrifugation, lead-silicate melts and glasses, microinhomogeneous structure, crystallization, X-ray phase analysis, IR-spectroscopy.
