Abstract
The paper studies the effect of an additive component PbO (up to 8,1 mol.%) on physical and chemical properties of the KCl–PbCl2 molten system. The study experimentally measures temperature of primary crystallization of selected electrolyte compositions. It uses the method of impedance measuring in cells with parallel electrodes and finds dependencies of electrolyte conductivity on the temperature and PbO content.
It uses Archimedean method to measure temperature dependence of the KCl–PbCl2 equimolar melt density containing up to 8,1 mol.% of lead oxide, and calculates values of molar volumes. The paper demonstrates that concentration dependence of the molar volume is of an extreme nature.
