T-x-y Diagrams for Reciprocal Systems PbX + CdI_2 = CdX + PbI_2 (X = S, Se, Te)

摘要

The first T-x-y diagrams for ternary reciprocal systems PbX + CdI_2 (X = S, Se, Te) are constructed. CdX-PbI_2 joins are stable diagonals. Phase equilibria involve solid solutions of the terminal components; for the X = S system, a Pb_5S_2I_6-based phase is also involved.
