Alumina powder is a ceramic of chemical composition Al2O3. The structure, the purity, the hardness and the specific surface area are the main characteristics of these powders.
The differences between the products may seem minimal but the physico-chemical properties between two ranges are completely different. The calcination time varies from one range to another, while some alumina are harder, others softer. The granulometry and distributions are also different.
Our wide range of alumina powder will allow you to select the product best suited to your application. Sintering, filling and polishing powders are available. A specific powder to prevent parts sticking during heat treatment is also available.
For specific grain sizes, we can offer customised sieving. Please get in touch.
Main Products alumina powder
100 Series: Alumina of medium purity, very high hardness, very low porosity and very low surface area.
- Chemical analysis: Al2O3 > 99.7% Na2O < 0.2%
- Granulometry: d50 between 1.5μm and 2.35mm
- Applications: Precision honing and polishing - Precision Sandblasting/Micro sandblasting - Compressed air surface treatment - Electrical insulation
200 Series: Alumina of high purity and hardness, low porosity and a specific surface area.
- Chemical analysis: Al2O3 = 99.85% Na2O = 0.06%-0.08%
- Granulometry: d50 between 3μm and 80μm
- Filler for synthetic resins - Filler for elastomers
300 Series:
This series is a little less pure than the 200 series and the specific surface area is a little larger. However, the product 007-0320 is much purer than the other alumina from the 300 and 200 series because it is specially made to measure to prevent smaller parts sticking during heat treatment.
- Chemical analysis: Al2O3 = 99.7% Na2O = 0.1%
- Granulometry: d50 = 0.50μm till 80μm
- Filler for synthetic resins - Filler for elastomers - Anti-stick agent
400 Series: Alumina of medium purity but with a very specific large surface area.
- Chemical analysis: Al2O3 = 99.6% Na2O = 0.3%
- Granulometry: d50 between 0.6μm and 80μm
- Incorporated with certain paints or inks, these alumina make it possible to obtain a particularly hard coating. The fineness of the alumina you use depends on the thickness of the layer of paint or ink.
