STUDY INTO CUTS In–CaSe AND In–CaInSe₂ OF THE TERNARY SYSTEM Ca–In–Se

Sections in In–CaSe and In–CaInSe₂ of the ternary system Ca–In–Se have been investigated by methods of physical-chemical analysis and phase diagrams. It has been established that the system In–CaSe is a pseudobinary of eutectic type and the system In–CaInSe₂ is nonquasibinary sections of ternary system Ca–In–Se. The confined areas of solid solutions were determined on basis of initial components. It was determined that solid solutions of CaSe are up to 2 mol.% In, and on basis of CaInSe₂ they are up to 5 mol.% In
