The crystal structure of cadmium-indium alloys rich in indium

The solubility of cadmium in indium has been determined by X-ray diffraction methods as 14.5 ± 0.5 atomic per cent at 20° C. The axial ratio of the face-centred tetragonal lattice of the indium-rich solid solution has been found to decrease with increasing cadmium-content, until at 4.5 atomic per cent the structure becomes face-centred cubic. No change in the volume of the indium atom is associated with the change in axial ratio.
