  • Abstract The thermal evolution of a sol–gel derived cobalt aluminate (CoAl2O4) of a spinel-type structure was studied. The samples were prepared by the sol–gel technique using aluminum-sec-butoxide [Al(OsBu)3] and cobalt nitrate hexahydrate Co(NO3)2 × 6H2O as starting materials and ethyl-acetoacetate (C6H10O3) as a chelating agent. The powder precursors were annealed at various temperatures ranging from 200 to 900 °C. The properties of products were characterized using differential thermal… CONTINUE READING
