Ĭobalt(II,III) oxide is used as an electrode in some lithium-ion batteries, possibly in the form of cobalt oxide nanoparticles.Ĭobalt compounds are potentially poisonous in large amounts. It is well known that the synthesis conditions have a great impact on the properties of the nanomaterial. Formula Molecular weight 74.9326 IUPAC Standard InChI:InChI1S/Co. Introduction The development of inorganic materials with special morphologies in the nanometer regime is of significant interest in material science and industry. These reaction are described by the following equilibrium:Ģ Co 3O 4 ⇌ 6 CoO + O 2 Applications Ĭobalt(II,III) oxide is used as a blue coloring agent for pottery enamel and glass, as an alternative to cobalt(II) oxide. Cobalt hydroxide oxide XRPD XPS NEXAFS SQUID 1. Tetrahedral coordination geometry of Co(II)ĭistorted octahedral coordination geometry of Co(III)ĭistorted tetrahedral coordination geometry of OĬobalt(II) oxide, CoO, converts to Co 3O 4 upon heating at around 600–700 ☌ in air. Interactive 3D chemistry animations of reaction mechanisms and 3D models of chemical structures for students studying University courses and advanced school. Structure Ĭo 3O 4 adopts the normal spinel structure, with Co 2+ ions in tetrahedral interstices and Co 3+ ions in the octahedral interstices of the cubic close-packed lattice of oxide anions. As a mixed valence compound, its formula is sometimes written as Co IICo III 2O 4 and sometimes as CoO Prior to joining CanAlaska in 2019 as chief operating officer. It is one of two well characterized cobalt oxides. 225.5 million pounds of uranium oxide grading 13.5 percent uranium oxide per tonne. Cobalt oxides comprise two readily accessible cation oxidation states: Co 2+ and Co 3+, which are thermodynamically competitive under common ambient. Cobalt(II,III) oxide is an inorganic compound with the formula Co 3O 4.
