The influence of basicities (CaO/SiO2) and contents of B2O3 and TiO2 on the structure of CaO-B2O3-SiO2-TiO2 glasses were examined. Experimental results indicate that TiO2 exists in the system in the form of [TiO4] as network former in range of 0-15% in mass. The degree of ...
Structure of CaO-B2O3-TiO2 glass system has been studied by Raman spectroscopy in this work. The in- fluences of TiO2 content and molar ratio of CaO to B2O3 on the structure of CaO-B2O3-TiO2 glasses were examined. Experimental results indicate that TiO2 exists in the form of [TiO4] ...
The structure ofAg2O-B2O3glasses are studied by the scale-transformed energy space sampling Monte Carlo method which is an efficient algorithm for investigating materials that have complex energy surface such as proteins and glasses. The high-energy barriers that exist between quasi-stable states can...
