Structural Studies of CaO-B2O3-TiO2 Glass System by Raman Spectroscopy
Structure of CaO-B2O3-TiO2 glass system has been studied by Raman spectroscopy in this work. The influences 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] or forms B-O-Ti lin...

| Summary: | Structure of CaO-B2O3-TiO2 glass system has been studied by Raman spectroscopy in this work. The influences 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] or forms B-O-Ti linkage, [BTi4O10]–1 structure units, in the system, and produces a certain destructive effects to large borate groups and induces to form some relatively small structure units. The increase of CaO does damages to the B-O-Ti linkage and large borate groups, simultaneously leading to the formation of relatively small units. Thus, both TiO2 and CaO impair borates network structure and weaken the glass-forming ability of borates in CaO-B2O3-TiO2 glass system. |
