Gamma-phase Aluminum Oxide (γ-Al₂O₃) nanoparticles are high-purity, ultra-fine powders with small particle size, high activity, and low melting temperature. These properties make them ideal for producing synthetic sapphire via thermal melting techniques.

With their large surface area and high catalytic activity, γ-Al₂O₃ nanoparticles can be formed into microporous spherical or honeycomb structures, making them excellent catalyst carriers for industrial processes such as petroleum refining, petrochemical reactions, and automotive exhaust purification. Additionally, they serve as high-performance analytical reagents and are widely used in advanced ceramics, electronics, and optical applications.

Applications:

• Catalysis: Catalyst and catalyst carrier in refining, petrochemical, and automotive exhaust purification.

• Transparent ceramics: High-pressure sodium lamps, EP-ROM windows.

• Gemstones & single crystals: Ruby, sapphire, yttrium aluminum garnet.

• Advanced ceramics: High-strength alumina ceramics, cutting tools, high-purity crucibles, furnace tubes, C substrates, packaging materials.

• Surface finishing: Polishing materials for glass, metals, semiconductors, plastics, tapes.

• Composite reinforcement: Enhances wear resistance in paints, rubbers, plastics, and waterproof materials.

• Electronics & optics: Vapor deposition, fluorescent materials, special glass, composite resins.

• Aerospace: Components such as aircraft wing leading edges.

Recommended Dosage:
Typically 1–5%, with optimization based on application-specific testing.
