DISSOLUTION BEHAVIOURS OF La IN KCl-NaCl AND LaCl_3-KCo-NaCl MELTS
La在KCL—NaCl和LaCl3—KCL—NaCl熔体中的溶解行为

The dissolution behaviours of La in KCl-NaCl and LaCl_3-KCl-NaClmelts have been studied by means of the see-through cell, cyclic voltammetry andEHMO of quantum chemistry. The La dissolved in KCl-NaCl melt is found to be ina metallic state, and dissolved in LaCl_3-KCl-NaCl melt ionized into La~(2+) which mayreact furthermore with surrounding La~(3+) to form atom cluster La_m~(n+).
