Electrical resistivity of solutions of barium in liquid sodium

Abstract

The electrical resistivity of solutions of barium in liquid sodium have been measured by a capillary technique which involves circulation of the liquid metal through the capillary by use of an electromagnetic pump. Resistivity values are reported for solutions containing up to 43 atom % barium, and at temperatures in the range 100–460 °C. In order to interpret the reactivity of dilute solutions, emphasis has been placed on the concentration range 0–12 atom % of barium, where resistivity increases almost linearly with barium concentration and with temperature. At the high concentrations, resistivity passes through a minimum with increase in temperature.
