About Aluminium oxide (α-phase) 99.9%

Vaqora Chemicals supplies Aluminium oxide (α-phase), an adsorbent registered under CAS number 1344-28-1, specified at 99.9% purity. The compound has the formula Al2O3, corresponding to a molecular weight of 101.96 g/mol. Its systematic (IUPAC) name is dialuminum. Tris(oxygen(2-)). Alternative names: Alumina and Aluminium oxide.

In its supplied form it is a white powder. Key physical data: a melting point of 2040 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for column chromatography, adsorption and purification, drying and decolourising and polymer and resin production. Our customers for this product work in academic and industrial research and polymers and plastics.

We offer Aluminium oxide (α-phase) in 100 g, 500 g and 2.5 kg packs with a batch-specific COA, and ship to customers worldwide.
