Summary:Cubic microparticles of Co sub(3)O sub(4) spinel were synthesized by calcination of CoCO sub(3) obtained using CoAl layered double hydroxide (LDH) as a unitary precursor through soft-chemical decomposition. The obtained cobalt spinel showed an exceptionally high electrical conductivity at room temperature. This is attributed to high concentrations of charge carriers (Co super(4+)), unique morphology, high reduction temperature and low activation barrier.
