Heat treatment-induced compositional and structural changes in the preparation of CuCrAlO4 and CuFeAlO4
Tóm tắt
The formation of the spinel oxide compounds CuCrAlO4 and CuFeAlO4 has been studied at the nanolevel using thermal analysis, X-ray diffraction, high-resolution elemental microscopy, and differential dissolution. The results demonstrate that, in the case of the synthesis procedure used in this study, spinel structures are formed by solid-state reactions. We have studied the dynamics of changes in the chemical and phase compositions, lattice parameters, structure, and morphology of spinel particles at temperatures of 600 and 900°C. Our findings are of practical interest in adjusting conditions for the formation of mixed oxide compounds with the spinel structure.
