(Changchun Institute of Applied Chemistry, Academia Sinica, Changchun 130022, China)
Abstract: The radial distribution Functions of molten salt solution LaF3—4LiF and LaF3—4KF systems were derived From X-ray difraction data at 1,083 K. The interionic distances in the melts were obtained, e. g. La3+—F- interaction was 0. 238 and 0. 233nm respectively in molten LaF3—4LiF and LaF3—4KF systems. The temperature and coulombic force of La3+ were discussed concerning the results of interionic distances in melt .
Key words: X-ray melt LaF3
