Emphasis of some physical and dynamical properties of inverted barium phosphate base glass

Melt-annealed zinc barium phosphate invert glass was produced. A mixture of borate (B2O3), cadmium oxide (CdO), and lead oxide (PbO) was added to the synthesized glass. B2O3 in the base glass formed P–O–B linkages with BO3 and BO4 structural units, with CdO acting as a modifier. PbO4 structural unit...
