✦ Synopsis
The kinetics of aluminium deposition from NaCI-AICI 3 , KCI-AICI 3 and CsCI-AICI 3 melts (C,rlc1 . = 3 x 10 -'-1 x 10 -3 mol em -3 ) was studied using the chronopotentiometric technique . It was found that in the system NaCI-AIC 3 the reduction of AI(III) species is controlled by diffusion only, while in the system KCI-AIC1 3 and CsCI-AICI 3 , a chemical reaction precedes the reduction step . In the two tatter systems the AI(III) in the complex anion AICI can be reduced also directly, if current density is sufficiently high .
