New glasses based on Sb2O3-PbO association have been synthesized and characterized. The limits for glass formation have been investigated in ternary systems encompassing trivalent oxides such as Al2O3, Ga2O3, and In2O3 as the third component. Fast quenching is required to prevent melt crystallization, which results in thin samples. Chemical analysis shows a rather good agreement between nominal and analyzed compositions. Glass transition temperature, T-g, ranges between 255 degrees C and 280 degrees C, depending on composition. Density and hardness have been measured for typical samples.
