The electric conductivity of molten lead silicates of various composition, 20 to 60 mole SiO2, was determined at the temperature ranging 800 to 1, 150°C. The conductivity increased with rising temperature and with increasing PbO-content. There are two discontinuities in the conductivity-composition curve; each corresponds to the composition of 2PbO·ESiO2 and PbO·ESiO2 respectively, the fact showing the presence of these compounds even in the melt. The conductivity of some samples was also studied while heating from the solidto the melt. The appearance of melt was shown by sudden change in the logarithm of conductivity-reciprocal of absolute temperature curve.
