Structure of molten salt
    Molten salt heat transfer is commonly used heat medium of molten salt composed of cations and anions. The interaction between ions including three parts. A electrostatic interaction, it is obey Coulomb's law of long range force; second is a short range repulsive force; three is van der Waals force.
    If the structure of the mathematical model of molten salt as a primary approximation, describing the structure of molten salt by electrostatic hard sphere model. That Yin, are charged with cationic radial hard sphere, and will force van Edward ignored or as a correction term. Due to the electrostatic interaction, the molten salt in each ion are counter ions surrounded by X ray diffraction the experimental results show that: compared with the crystal structure of molten salt cation instead of bardo, nearest distance increased, but decreased slightly, but the first nearest neighbor of each ion number (coordination number) is significantly reduced in the crystal. This shows that the molten salt deposit in the irregular distribution of the gap or space. Two kinds of molten salt mixed melting after the formation of the salt solution, the structure is similar. According to the potential energy equation of ion interaction, simulation of ion in molten salt movement and distribution are calculated by computer, many physical molten salt or molten salt solution Chemical property.
