Abstract: A precursor Co2 (OH)2CO3, was prepared by solid state reaction with Co(NO3)2.6H2O and NH4HCO3 at ambient temperature. Nanophase Co3O4 with the average of 13nm was obtained by decomposed the precursor about 3h at 250°C. The composition, size, appearance and properties of the product were studied by XRD, TG-DTA, TEM and SEM.

Key words: Co3O4, solid state reaction, nanomater, powder
