Phase boundaries of the (YbTe) (N...) (PbTe)(1-N...) and (YbTe) (N...) (SnTe)(1-N...) solid solution series

摘要

We derive analytical expressions for the free energy of mixing of (YbTe) (N...) (PbTe)(1-N...) and (YbTe) (N...) (SnTe)(1-N...) solid solutions in the temperature range 600-1095 K and accurately determine the location of their phase boundaries. D cent-N...-N integral relations for the solidus surface and the spinodal decomposition of solid solutions in the pseudoternary system YbTe-PbTe-SnTe are found.
