Alumina powder for ceramics, refractories and polishing
Calcined and polishing-grade aluminium oxide powders in a range of particle sizes for industrial use.
Overview
Alumina (aluminium oxide) is valued for its hardness, thermal stability and chemical resistance. It is used across ceramics, refractories, abrasives, coatings and catalyst supports.
We supply alumina powders matched to your particle-size and purity requirements.

Frequently asked questions
What is the difference between calcined and polishing alumina?
Calcined alumina is a general-purpose grade for ceramics and refractories. Polishing grades are finer and more uniform to deliver a consistent surface finish. We will help you choose.
Can you supply a specific D50?
Yes. Share the target particle size and application, and we will confirm the closest available grade.
Is alumina safe to handle?
Alumina is a non-toxic material, but fine dust should be handled with normal dust controls. An MSDS is available on request.
