【Abstract】 Effects of the oxides of some V-group elements P, Sb, Bi on the glass formation region of PbO-B2O3-SiO2 system has been studied. Glass properties such as devitrification tendency, micro hardness, thermal expansion coefficient, softening temperature, chemical durability etc, have been determined. It is shown that some of the glasses can be used as soldering and encapsulating materials.更多还原
