Structure model of glasses for PbO-Bi//2O//3-B//2O//3 system

The glasses of B//2O//3 contents above 50% (mole percent) in PbO- Bi//2O//3-B//2O//3 system were prepared by conventional melt quenching technology. The glass structure contains two kinds of matted crystal related to the mole ratios of PbO versus Bi//2O//3 and the addition contents of B//2O//3. Different boron- oxygen rings such as boroxol ring and triborate ring were found in the glass structure. (Edited author abstract) 5 Refs.
