Fine-grained CoO powders were prepared directly by solid phase synthesis-heating blasting de- composition with COSO4 ·7H2O and NH4 HCO3 as the materials. And their composition and morphology were characterized by SEM,XRD,IR and chemical titration. The results show that fine-grained CoO pow- ders of pure octahedral morphology can be obtained under the conditions of excessive NH4 HCO3 and 650-750 ℃ reaction temperature,having the advantages of simple process and high efficiency.
