Solubility Limits in Binary (Ca,Mn) Chalcogenides

Solid solubilities progressively decrease in the systems CaS‐MnS, CaSe‐MnSe, and CaTe‐MnTe. In CaS‐MnS, full solid miscibility extends from 1150° to 1500°C, the liquidus minimum. With CaSe‐MnSe, this range is 1070° to 1340°C. The solid miscibility gap between CaTe and cubic MnTe intercepts the liquidus as a eutectic at 1050°C. The solid solutions follow Vegard's law closely.
