Dimensional Analyisis of Some Physical Properties of Molten Salts

Based on electrostatic potential hard sphere model,the dimensional analysis of the configura-tional integral of molten salts and related physical properties has been made. The result indicates the equality of radius ratio between cation and anion Rc/Ra is the necessary condition of the similarity of molten salt systems. Using the result of dimensional analysis and artificial neural network method,the data of the surface tension,vapor pressure and melting point of some molten salts are correlated and predicted,with good results.
