Characteristic
Cobalt(II,III) oxide is an inorganic compound with the formula Co3O4. It is one of two well characterized cobalt oxides. It is a black antiferromagnetic solid. As a mixed valence compound, its formula is sometimes written as CoIICoIII2O4 and sometimes as CoO•Co2O3.
Chemical formula:Co3O4
CoO.Co2O3
Molar mass:240.80 g/mol
Appearance:black solid
Density:6.11 g/cm3
Melting point:895 °C (1,643 °F; 1,168 K)
Boiling point:900 °C (1,650 °F; 1,170 K) (decomposes)
Solubility in water:Insoluble
Solubility:soluble in acids and alkalis
Magnetic susceptibility (χ):+7380·10−6 cm3/mol
