This can explain the cobalt oxidation observed during thermal cycling at 900°C. Does cobalt oxidize easily? It is readily oxidized with water and oxygen to brown cobalt(III) hydroxide (Co(OH)3). At temperatures of 600–700 °C, CoO oxidizes to the blue cobalt(II,III) oxide (Co3O4), which has a spinel structure. At what temperature Read more…
