Cobalt Oxide 72% Ceramic Pigment

Cobalt Oxide 72% Ceramic Pigment (CAS 1308-06-1, molecular formula Co3O4) is a raw material for tile, sanitaryware, tableware and refractory production, where particle size and impurity profile drive fired colour and body strength. China Chemicals supplies it at Co 72% min in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Tricobalt Tetroxide, Cobaltosic Oxide, Cobalt Black. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Blue colourant in ceramic glaze and porcelain enamel
Blue and black pigment in glass manufacture
Precursor for lithium cobalt oxide battery cathode
Catalyst in petrochemical and oxidation processes
Adhesion promoter in steel-cord rubber compounds
