Aluminium Oxide – 500 gram Packs

Aluminium Oxide, also known as alumina, is an inorganic compound of aluminium and oxygen with the chemical formula Al2O3. It has a molecular weight of approximately 101.96 g/mol and commonly appears as a white crystalline powder. Aluminium Oxide is insoluble in water and exhibits properties that vary with its crystalline form, surface area, and preparation method. It is widely used in laboratory work involving inorganic solids, adsorption, chromatography, and materials characterisation. In educational and research laboratories, alumina can serve as a stationary phase in suitable chromatographic procedures and as a material for studying oxide chemistry. Its suitability for a particular application depends on the grade, particle size, surface properties, and crystalline modification required. Laboratories should select the appropriate form and follow suitable dust-control and handling procedures.

Frequently Asked Questions About Aluminium Oxide

What is Aluminium Oxide used for in laboratories?

Aluminium Oxide is used in chromatography, adsorption studies, materials research, and inorganic chemistry investigations. Chromatographic performance depends on the alumina grade, surface activity, and particle size specified by the method.

What is the molecular formula of Aluminium Oxide?

Aluminium Oxide has the formula Al2O3 and a molecular weight of approximately 101.96 g/mol. Different crystalline forms have the same chemical formula but can exhibit different physical and surface properties.

What is the CAS number of Aluminium Oxide?

The CAS Registry Number for Aluminium Oxide is 1344-28-1. Special forms such as particular minerals or prepared materials may have additional identifiers, so confirm the product description when selecting a specific grade.

Which Aluminium Oxide grade is suitable for chromatography?

Chromatography requires an alumina grade with suitable particle size and surface activity. The appropriate grade depends on the compounds being separated and the method conditions; general laboratory-grade alumina should not automatically be assumed suitable for every separation.

How should Aluminium Oxide be stored?

Keep the powder in a tightly closed container in a clean, dry location to limit contamination and moisture uptake. Avoid generating airborne dust and follow the product Safety Data Sheet for handling and disposal guidance.

Storage Conditions for Aluminium Oxide

Store in a tightly closed, labelled container in a dry, well-ventilated area. Protect the powder from contamination and excessive moisture, particularly when the material is intended for surface-sensitive applications such as chromatography. Keep it separated from incompatible substances identified in the Safety Data Sheet.

Precautions for Handling Aluminium Oxide

Wear suitable gloves, protective clothing, and safety glasses. Avoid inhaling dust and use appropriate ventilation during weighing or transfer. Prevent contact with the eyes and minimise dust generation. Follow the current Safety Data Sheet and institutional procedures for spill cleanup and waste disposal.
