Abstract:
In earlier publication, it was reported that the dispersed phase of CuAlO2 delafossite can be prepared at
low temperatures during heat treatment of molten aluminum nitrate and solid CuO. Our studies
disproved this conclusion. In fact, the interaction of aluminum nitrate with copper oxide proceeds even
at a temperature below 130 1C with the formation of copper nitrates. A further heating results in
decomposition of the nitrates and formation of copper oxide by the known three-step mechanism. The
formation of CuAlO2 delafossite structure occurs in this system at temperatures not less than 990 1C and
is accompanied by absorption of heat and release of oxygen.
