| 摘 要： | The microscopic structure of certain molten-salt-liquid-metal solutions has been investigated by quantum chemical method. It is indicated that (ⅰ) Li_(n 1)~(n ) or Li_(n 2)~(n ) ions form in Li-LiF melt. The valence electrons of Li atoms delocalize into all vacant orbitals of neighboring cations; (ⅱ) lithium fluoride, dissolving in liquid lithium, forms F~- ions in liquid metal, and the vacant orbitals of Li~ ions of the salt take part in the delocalization with the electrons of metallic bond. It is this delocalizatin energy that makes this solution thermodynamically stable; (ⅲ) Mg_2~(2 ) is unstable as compared with Mg~ or Mg_2~ . The experimental results of mass-spectroscopy also indicate the existence of Mg~ abd Mg_2~ , but not Mg_2~(2 ). The state of Mg dissolving in molten salt is discussed based on the results mentioned above.
