A study has been made of the effects of 0.05 wt.% of Ag, Au, Bi, Cu, Hg, In, Mg, Pb, Sb, Sn, and Zn on the cadmium density during cyclic thermal treatment in the temperature range 20-300 °C. The density decreases if the impurity is relatively insoluble and forms a eutectic system with cadmium. On the other hand, the density may not change if the maximum temperature of the cycle does not exceed the melting point of this eutectic system, or if the samples are not subjected to sufficiently high thermal stresses.
