Cobalt oxide (II,III) News & Market Updates

The structural difference comes down to crystal field stabilization. Co(III) is a low-spin d6 ion with a very large splitting energy, so it strongly prefers octahedral sites, while Co(II) is high-spin d7 and settles into tetrahedral sites. That gives Co3O4 a normal spinel…

The three products diverge because of cobalt content and downstream destination. Cobalt metal, at roughly 286,000-295,000 yuan per tonne, serves superalloys, defense and exports. Co3O4, quoted around 255,000-275,000 yuan per tonne, feeds 3C lithium cobalt oxide, where one tonne…

Industrial routes start from a cobalt salt, usually cobalt chloride or sulfate, then build a uniform precursor before calcination. One path reacts cobalt chloride with ammonium bicarbonate to form cobalt carbonate, which is then calcined at high temperature. A second, now…
