Thermal Stability of CuCr&sub(1-x)Zr&sub(x)Se&sub(2) with x *{ 0.2 / A.S.Shkvarin, S.V.Sumnikov, [a.o.] // Chemical Physics Letters. – 2025. – Vol. 865. – P. 141942. – URL: https://doi.org/10.1016/j.cplett.2025.141942. – Bibliogr.: 28.

Substitution solid solutions CuCr&sub(1-x)Zr&sub(x)Se&sub(2), x = 0–0.2 have been synthesized for the first time. The crystal structure and phase equilibria of these samples were studied in the temperature range of 100–700 &sup(o)C. It was found that the delafossite-like crystal structure is stable in the whole temperature and concentration range studied. It was found that parasitic phases, binary copper and chromium selenides and spinels CuCr&sub(2)Se&sub(4) and Cu(Cr&sub(1-x)Zr&sub(x))&sub(2)Se&sub(4), are formed during the synthesis. Their appearance is because doping with zirconium does not affect the crystal structure. Instead, it affects the thermodynamic stability of the CuCr&sub(1-x)Zr&sub(x)Se&sub(2) solid solution with a delafossite-like structure.
