Solid solutions AgxCu2-xHgI4 prepared by a solution method were characterised by powder X-ray diffraction, differential scanning calorimetry (DSC) and electrical conductivity. X-ray diffractograms showed tetragonal phases over the whole range expept for 1.14 ≤ × ≤ 1.30 where a single cubic phase was seen. DSC showed a strong compositional dependence in the order-disorder transition temperature. Temperature variation of electrical conductivity carried out for all compositions showed an increase in conductivity by two orders of magnitude at the transition temperature. The composition x=1.14 having a maximum room temperature conductivity with a minimum transition temperature has the characteristics of an eutectoid of the Ag2Hgl4-Cu2HgI4 system. © 1991.
