Abstract : Sodium chloride crystals doped with F- anions and divalent cations as impurities show three new well defined independent relaxation peaks, B, C and D when analysed by ionic thermocurrent technique I.T.C

The microscopic nature of the defects that give rise to the observed dipolar relaxation is not known. Peaks B, C and D have their maxima in temperatures below that of the isolated divalent ion peak A such that TD < TC < TB < TA. The aggregation kinetics between Pb+ + and F- ions was measured at R.T. and is well described by the reaction Pb+ + + F- → B + C. Peak D does not change in intensity during this process.
