Popis: | The process of the reduction spherical Co3O4 particles to metallic Co in a continuous H2 flow at the temperature interval (200–350°C) was studied using the XRD method. The phase analysis of the reduced particles showed their non-single state (the coexistence of α-Co and β-Co). The β-Co concentration increases with an increase in the reduction temperature. |
