Cobalt Oxide Supplier in Malaysia
- Also known as
- cobalt(II,III) Oxide
- Cobalt Tetroxide
- Tricobalt Tetraoxide
- Co3O4
Cobalt oxide supplier enquiries in Malaysia are normally for cobalt(II,III) oxide, Co3O4, also written cobalt tetroxide or tricobalt tetraoxide. It is a black powder used in ceramic and glass colour, catalyst preparation, battery materials and electronic ceramics.
Technical, ceramic, pigment, catalyst and higher-purity grades are selected by cobalt basis, particle size and impurity limits. The required profile depends on whether the powder is fired into a glaze, used as a catalyst feedstock or processed into an advanced material.
Ceramic and glass makers use cobalt oxide to develop controlled colour, while chemical manufacturers use it as a feedstock for cobalt compounds. Catalyst, battery and laboratory buyers may require tighter controls on phase, moisture or trace metals than a general technical enquiry.
This page is for Co3O4, not cobalt(II) oxide, CoO, or a soluble cobalt salt. Send the phase, grade, specification, quantity and delivery location with your enquiry, and availability, packing, documentation, route and timing are confirmed with the quotation.

Common questions about cobalt oxide
What identity does the cobalt oxide page cover?
This page covers cobalt(II,III) oxide, Co3O4, also called cobalt tetroxide or tricobalt tetraoxide. It is normally a black powder used in ceramics, glass, catalysts and materials work. State the oxide phase when your specification distinguishes Co3O4 from cobalt(II) oxide.
Is cobalt oxide the same as cobalt(II) oxide?
No. They are different oxide identities. This page is for mixed-valence cobalt(II,III) oxide, Co3O4, while cobalt(II) oxide, CoO, has a different composition and its own specification. Request the phase named by the process instead of using the generic term alone.
Which cobalt oxide grade suits ceramic or glass colour?
Ceramic and pigment grades are selected for particle size, fired colour and impurity limits. Send the glaze or glass formulation, target shade and any trace-metal limits so the quoted Co3O4 grade can be matched to the firing process.
Why do catalyst and battery buyers specify particle size?
Particle size affects surface area, dispersion, reaction behaviour and the way the powder is charged into a process. Give the required distribution, cobalt basis and impurity limits with the catalyst or materials specification rather than relying on colour alone.
What specifications should be included in a cobalt oxide enquiry?
State the oxide phase, grade, cobalt content or assay basis, particle-size distribution, moisture and trace-metal limits, quantity and delivery location. Include the ceramic, catalyst, battery or electronic-material use when it determines the acceptable grade.
How should cobalt oxide powder be stored?
Keep it in closed containers in a dry store and minimise dust during transfer or blending. Follow the safety information issued with the quoted grade and apply the handling controls required by the buyer's own workplace procedure.
