Abstract
The solubilities of the group II elements Cd, Zn, Hg, Ca and Mg in PbTe are compared over the temperature range 250 to 800° C. Cd, Zn and Mg have retrograde solubilities whilst Hg and Ca are virtually insoluble in “as-grown” material. A consequence of these solubilities is a change in the properties of the alloys compared with PbTe. Thus the phase widths of the Cd/PbTe, Mg/PbTe and Zn/PbTe systems differ from that of PbTe. With the exception of the Zn/PbTe system, (where there is reasonable evidence to support the solubility of Zn in PbTe) there is a significant change in all measured electrical properties compared with PbTe.
