| Abstract: | Co3O4 ultrafine particles (UFP) were prepared from CoCl2 by colloidal chemical method. The most favorable experiment conditions for the preparation of Co3O4 UFP were studied. XRD, DTA, TG, IR and TEM examinations were used to discribe the characteristic of the sample. The spherical amorphous ultrafine Co3O4 product has average diameters of 4. 0 nm, with good dispersity and transparency in many organic solvents. When heat-treated at 800 K for 3 hours, cubic crystal Co3O4 UFP can be obtained, the average crystal grain size is 6. 0 nm. |
