Abstract

Copper-cobalt oxide spinels with a common formula Cu x Co3−x O4 (0≤x≤1.0) have been prepared by thermal decomposition at 350° C in air of single-phase mixed basic nitrate precursors (Cu, Co)2(OH)3NO3. The formation of the oxide phase during the thermal treatment has been associated with a diffusionless mode of transformation, established for some hydroxides and hydroxysalts with a layer-type structure.
