Annotation

The process of spherical particles Co$_3$O$_4$ reduction up to metallic Co in continuous H2 flow at the temperature intervals (200 – 300 ̊C) was studied by means of XRD method. The phase analysis of reduced particles showed their non-single state (coexistence of α-Co and β-Co). β-Co concentration increases with reduction temperature grow.
