Aluminium Oxide Powder (Alumina) Supplier in Malaysia
- Also known as
- Alumina
- Al2O3
- Aluminum Oxide
- Aluminium Trioxide
ChemTrade supplies aluminium oxide powder to industrial buyers across Malaysia. Sold as alumina or Al2O3, it is the workhorse ceramic oxide: hard, chemically inert, and stable well above the temperature at which most materials fail.
It splits into grades that are not interchangeable. Calcined alumina is the general purpose powder for ceramics, glaze, glass and polishing, and activated alumina is a porous adsorbent for gas drying and for fluoride and arsenic removal. Fused alumina is the abrasive grit for blasting and grinding, and tabular alumina is the dense refractory grade.
Note that aluminium oxide is not aluminium powder. One is an inert ceramic, the other a reactive combustible metal. If your specification reads Al2O3 or alumina, this is the product.
We hold calcined alumina in 25 kg bags and source the abrasive, activated and refractory grades to order. Tell us the grade, and the grit or mesh size if the process needs one, and we will quote.

Aluminium Oxide grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Calcined alumina | white powder | — | The general purpose grade and the one we hold. Goes into ceramic bodies, glazes, refractory mixes, glass batch and polishing compounds, and serves as a catalyst carrier in chemical processing. | 25 kg bag |
| Activated alumina | white spheres or granules | — | A high surface area adsorbent rather than a filler. Used as a desiccant in compressed air and gas dryers, and in water treatment for fluoride and arsenic removal. Sourced to order against your mesh size and pore specification. | bag or drum |
| Fused alumina, brown or white | crushed grit | — | The abrasive form, harder and denser than calcined alumina because it has been melted and recrystallised. For blast cleaning, surface preparation, grinding wheels and lapping. Tell us the grit designation your process calls for. | 25 kg bag |
| Tabular alumina | sintered granules or powder | — | Low porosity and high refractoriness for monolithic refractory castables, kiln furniture and furnace linings. Sourced to order against the sizing the castable recipe needs. | bag or bulk bag |

Aluminium Oxide applications
Safety and handling
Not classified as a dangerous good, and no licence is required to buy it. The dust is a nuisance respirable particulate, so keep bags closed, avoid raising clouds when charging, and use local extraction or a dust mask where handling is open. Wear gloves and safety glasses, because the powder is abrasive and mechanically irritating to skin and eyes. Store dry: it is chemically stable and does not degrade, but the fine grades cake once damp.
Common questions about aluminium oxide
Which grade do I need, calcined, activated, fused or tabular?
It follows the job. Calcined alumina is the general purpose powder for ceramics, glaze, glass and polishing. Activated alumina is a porous adsorbent for drying gas or stripping fluoride and arsenic from water. Fused alumina is the hard abrasive grit for blasting and grinding, and tabular alumina is the low porosity refractory grade. Describe the process and we will point at the right one.
Is aluminium oxide the same as aluminium powder?
No, and ordering the wrong one is a real problem. Aluminium powder is the metal, it is reactive and a combustible dust. Aluminium oxide is the fully oxidised ceramic, inert and non-combustible. If your specification says Al2O3 or alumina, you want this product.
Do you sell it as an abrasive grit, and in which sizes?
Yes, brown and white fused alumina for blasting and grinding, sourced against the grit designation you specify. We do not publish a size list because the range is wide and it is set by your equipment and the finish you need, so send the designation your current supplier ships and we will match it.
What does it cost?
It depends on the grade far more than on the quantity: fused abrasive grit, calcined powder and activated spheres are different products at different prices. Alumina also tracks the aluminium market, so we quote a current price with a stated validity period. Send the form and tonnage for a figure.
Is alumina the same thing as aluminium oxide?
Yes. Alumina is the trade name, aluminium oxide is the chemical name, and Al2O3 is the formula. The ceramics and refractory trade tends to say alumina and purchasing documents tend to say aluminium oxide, but both refer to CAS 1344-28-1.
What packing is available, and do I need a licence?
No licence is needed, it is not a scheduled poison and not a dangerous good for transport. Standard packing is a 25 kg bag, with bulk bags available on the refractory and abrasive grades. We work with several producers, so ask if you need a size that is not standard.
