· JVASP-29509· Cr3O8

Cr₃O₈ is a mixed-valence chromium oxide ceramic compound belonging to the family of chromium oxides used in advanced ceramics and materials research. While not as widely commercialized as Cr₂O₃, this material is investigated for applications requiring specific oxidation states and chemical reactivity, particularly in catalysis, materials chemistry, and specialized ceramic systems where chromium's multiple valence states provide functional advantages.
