 Title    Internal Cation Mobilities in Molten (K, Dy 1/3 )C1  
 Abstract    Internal cation mobility ratios in the molten system KCl-DyCl 3 have been measured at 1093 K by Klemm's countercurrent electromigration method. From these, and data available on the con-ductivities and molar volumes of the mixtures, the internal mobilities b of both cations have been calculated. With increasing concentration of Dy, b K decreases. The decrease of b K is attributed to the tranquilization effect by Dy 3+ ions which strongly interact with Cl~ ions. With increasing concentration of K + , b Dy decreases; this may be attributed to the stronger association of Dy 3+ with CP ions due to the enhanced charge asymmetry of the two cations neighboring to the CP ions. It could not been clarified whether a species such as [DyCl 6 ] 3_ is also an electrically-conducting species in the K + rich range.

 Title    Internal Mobilities in the Molten Binary Systems (Tl, K)N0 3 and (Tl, Cs)N0 3  
 Abstract    Ratios of internal cation mobilities in the molten binary systems (Tl, K)NO a and (Tl, Cs)N0 3 have been measured by the Klemm method. From these and the data available on the densities and electric conductivities, the internal mobilities b have been calculated. While generally in the mixtures of T1N0 3 with alkali nitrates at constant temperature the conductivities and internal mobilities decrease with increasing molar volume, in (Tl, K)N0 3 they decrease with decreasing molar volume. This is explained by the high polarizability of the Tl + ions.
