Abstract

The surface tension and the density of molten Li₂CO₃-X₂CO₃ (X : Na, K, Rb, and Cs) and Na₂CO₃-Y₂CO₃ (Y : K, Rb, and Cs) binary carbonate systems were measured using maximum bubble pressure technique. The addition of Rb₂CO₃ or Cs₂CO₃ to Li₂CO₃ or Na₂CO₃ effectively decreases the surface tension of mixtures. At constant temperature, the relationship between surface tension and composition in all binary carbonate systems was well correlated by the Guggenheim’s Equation for regular solution. The molar volume of Li₂CO₃-Rb₂CO₃ and Li₂CO₃-Cs₂CO₃ systems shows positive deviation from additivity.
