Product Description

Product Description

Aluminum Oxide (Alumina, Al2O3)

Aluminum oxide, commonly known as alumina, is a high-hardness ceramic compound with widespread industrial applications due to its thermal stability, electrical insulation, and chemical resistance.

 

Key Properties

• Molar Mass: 101.96 g/mol

• Appearance: White crystalline powder (corundum) or transparent crystals (sapphire/ruby)

• Density: 3.95-4.1 g/cm³

• Melting Point: 2,072°C

• Boiling Point: 2,977°C

• Hardness: 9 on Mohs scale (second only to diamond)

• Solubility: Insoluble in water; reacts with acids/bases at high temperatures

 

Forms & Production

1.  

   • Most stable form, produced by calcining aluminum hydroxide at >1,200°C.

   • Used in abrasives, refractories, and synthetic gemstones (rubies/sapphires).

     • Porous, high-surface-area form for catalysis and adsorbents.

2. Synthetic Methods:

   • Bayer Process: Refining bauxite ore with NaOH.

   • Electrolysis: Used to produce aluminum metal.

 

Applications

1. Industrial

   • Abrasives: Sandpapers, grinding wheels, and polishing compounds.

   • Refractories: Linings for furnaces (withstands >1,800°C).

2. Electronics

   • Insulators: Substrates for integrated circuits.

3. Medical & Consumer Goods

   • Bioceramics: Hip/knee implants (inert and wear-resistant).

   • Transparent Armor: Bullet-resistant windows.

4. Catalysis & Environment

   • Catalyst Support: For petroleum refining.

   • Water Purification: Adsorbs heavy metals.
