Cobalt(II,III) Oxide (Co3O4) Powder, Battery Grade (Co 73-73.5%)

Cat No:BMSPEM-0408

Description

This cobaltosic oxide (Co3O4) powder from Eata Battery is a black, spherical cobalt oxide for battery material synthesis. Specifications: Co content 73-73.5%; Li 0.10% or lower; Fe and Mn 0.001% or lower; Na 0.1% or lower; Ca 0.03% or lower; Cu and Mg 0.02% or lower; Pd 0.01% or lower; NO3- 0.05% or lower; SO42- and Cl- at trace levels. Physical properties: formula weight 240.80; tap density above 2.0 g/cm3; apparent density above 0.5 g/cm3; particle size D50 8-20 um; single spinel phase without other phases. The material absorbs moisture when exposed to air but does not form hydrates, is readily soluble in nitric acid, decomposes into cobalt oxide (CoO) when heated to 1200 degrees C, and is reduced to metallic cobalt at about 900 degrees C in a hydrogen atmosphere.
