Chinese Name: 電池級四氧化三鈷
English name: Cobalt oxide (II,III)
Chinese alias: cobaltosic oxide (II,III)
CAS No.: 1308-06-1
Molecular formula: Co3O4
Molecular weight: 240.7972
Product Application: Power Battery Materials
Black or grayish black powder. The bulk density is 0.5-1.5g/cm3, and the tap density is 2.0-3.0g/cm3. It is the product of cobalt monoxide and cobaltic oxide. When exposed in air, it is easy to absorb water but does not generate hydrate. It is soluble in nitric acid. When heated to over 1200℃, it will decompose into cobalt oxide. When heated strongly to 900℃ in hydrogen flame, it is reduced to metallic cobalt.
