Аннотация

Mixed copper-containing spinel-type compounds CuCr₁Fe₁O₄, CuCr₁Al₁O₄ and CuFe₁Al₁O₄ were studied by means of XRD and HREM after calcination at 650 °C in the air and treatments in a hydrogen-containing medium at 270–210 °C (H₂:He = 5:95; H₂:CO:H₂O = 50:7:43). The effect of the chemical nature of Mе³⁺ cation on the structural-morphological characteristics of oxide systems and their transformations in a reducing medium was investigated. It was shown that the nature of Me³⁺ cation makes it possible to control the structural characteristics, particularly in the reduced state.
