Research of Manufacturing Battery-Grade Co<sub>3</sub>O<sub>4</sub> of Octahedron-Shape

For getting higher quality and octahedron shape product Co 3 O 4 , the article studies precursor baked temperature, baked temperature route, baked condition affecting on apparent density, then points out obtaining octahedron shape Co 3 O 4 technology. Test shows if the practice is accorded to the technology strictly, demanding standard Co 3 O 4 can be obtained.
