Electrical properties of some copper-containing phosphate glasses

The electrical properties of some copper-containing phosphate glasses were studied. The electrical conductivity value for all studied glasses were presented at room temperature and Cu +/Cu tot ratios. The conductivities of ternary glasses MgO-, CaO-, ZnO- and PbO-containing copper phosphate glasses showed that as the divalent ionic radius increases, the room temperature conductivities decrease in the order MgO>ZnO>CaO. CuO in copper metaphosphate glass results in an increase in the electrical conductivity, replacing alkali metal oxide for 20 mol.%.
