Aluminium Oxide (Al₂O₃) – High-Purity Laboratory and Industrial Chemical

Aluminium Oxide, also known as Alumina, is a white, odorless crystalline powder widely used in chemistry laboratories, industrial manufacturing, and scientific research. It is an amphoteric oxide, meaning it can react both as an acid and a base. Chemically represented as Al₂O₃, this compound is one of the most important and versatile oxides of aluminium, known for its high melting point, thermal stability, and chemical resistance.

At Labtex Bangladesh (Labtexbd.com), we supply high-quality Aluminium Oxide suitable for analytical, laboratory, and industrial applications. Whether you are conducting research, chemical analysis, or material synthesis, our aluminium oxide ensures precision, consistency, and purity for all your experiments.

🔬 Laboratory Uses of Aluminium Oxide

Aluminium Oxide has a wide range of laboratory and scientific applications:

1. Chromatography Adsorbent:
   In chemistry and biochemistry labs, Aluminium Oxide (Al₂O₃) is used as an adsorbent in column chromatography for the separation and purification of chemical compounds.

2. Catalyst and Catalyst Support:
   It serves as a catalyst in various chemical reactions, including hydrogenation and oxidation, and as a support for other catalytic materials.

3. Analytical Chemistry:
   Aluminium Oxide is used in acid-base titration and gravimetric analysis where high-purity materials are essential.

4. Desiccant and Drying Agent:
   Its porous form absorbs moisture, making it an excellent drying agent for gases and solvents.

5. Sample Preparation:
   Used as a polishing and grinding material for preparing metallurgical samples before microscopic examination.

6. pH Control and Neutralization:
   Due to its amphoteric nature, it can react with both acids and bases to neutralize chemical systems.

🧭 Industrial Applications of Aluminium Oxide

Beyond laboratory use, Aluminium Oxide is also a critical industrial raw material:

• Abrasive Material: Used in sandpapers, grinding wheels, and polishing compounds due to its exceptional hardness.
• Ceramics and Glass Manufacturing: A key component in making high-strength ceramics and heat-resistant glass.
• Electronics: Used as an insulator in electrical and electronic components.
• Catalyst Carrier: Serves as a carrier for catalysts in chemical and petrochemical industries.
• Water Filtration: Acts as a filtering medium in water purification systems.

🧪 How to Use Aluminium Oxide in the Laboratory

1. As a Chromatographic Material:

   • Pack the chromatography column with Aluminium Oxide.

   • Pass the mixture through the column to separate components based on adsorption differences.

2. As a Drying Agent:

   • Place a small amount in a drying tube or desiccator to absorb moisture from gases or liquids.

3. In Catalyst Preparation:

   • Mix Aluminium Oxide powder with other chemicals to prepare catalytic materials.

4. In Polishing:

   • Use finely ground Al₂O₃ as a polishing medium for metal or glass samples.

Always wear gloves and a mask while handling the powder to avoid inhalation or direct contact.

⚠️ Safety and Handling Information

While Aluminium Oxide is relatively stable and non-toxic, proper laboratory safety practices are necessary:

• Avoid inhaling fine dust particles.
• Wear safety goggles, gloves, and a lab coat.
• Use in a ventilated workspace.
• Store in a dry, cool place, away from acids and moisture.
• Dispose of residues following standard chemical waste regulations.
