The character of chemical interaction in the CaIn₂–CaTe  system has been studied using the methods of differential thermal analysis, X-ray dif­fraction, micro structural analysis, and density measurements, and its state diagram has been cons­truc­ted. It has been established that the latter is a quasi-binary section of the ternary system Ca–In–Te. Com­po­unds CaIn₂ and CaTe form eutectic containing 15 mol. % CaTe, which melts at 760⁰C. At room temperature, solubility, based on CaIn₂ reaches up to 2 mol.% CaTe, and   on the basis of CaTe ~3 mol. % CaIn₂
