Formation of autocomplexes in halide melts of trivalent metals
Chemical equilibrium with respect to the dissociation of charged autocomplexes (MX6)3− in ionic melts of the MX3 type is analyzed. The chemical equilibrium M3+ + 6X− = (MX6)3− in salt melts of trivalent metal halides shifts strongly toward dissociation, due to the electrostatic interactions between charged particles in the melts.
