Aluminum Oxide Nanopowder Water Dispersion (AL2O3, Alpha, 20wt%, 30nm)

Aluminum Oxide Nanopowder Water Dispersion (AL₂O₃, Alpha, 20 wt%, 30 nm) is a liquid suspension of aluminum oxide (Al₂O₃) nanoparticles dispersed in water. Here’s a detailed explanation of its properties and applications:

1. Composition:

• Aluminum Oxide (Al₂O₃):
  • A ceramic material with excellent thermal, mechanical, and electrical properties.
  • Exists in different crystalline forms; in this case, Alpha (α) is the most stable and thermally robust phase.
• Nanopowder:
  • Nanoparticles with an average diameter of 30 nanometers (nm).
  • The small size gives a high surface area, enhancing reactivity and effectiveness.
• Water Dispersion:
  • The nanoparticles are evenly suspended in water, ensuring uniform distribution in applications.
• 20 wt%:
  • Indicates that 20% of the dispersion by weight consists of aluminum oxide nanoparticles, with the remainder being water.

2. Key Properties:

• Alpha Phase:
  • Stable at high temperatures and resistant to phase transformations.
• Nano-Scale Particles:
  • Provide high surface area and reactivity.
  • Improve dispersion and integration into matrices or coatings.
• Water-Based:
  • Environmentally friendly and easy to handle compared to organic solvents.
• Thermal Conductivity:
  • High heat dissipation capabilities, making it suitable for thermal management.
• Electrical Insulation:
  • High dielectric strength, ideal for insulating applications.
• Chemical Stability:
  • Resistant to corrosion and chemical attack.

3. Applications:

• Ceramics:
  • Enhances strength, hardness, and thermal stability in advanced ceramics.
• Coatings:
  • Used in thermal barrier coatings for high-temperature applications (e.g., turbines, engines).
• Polishing:
  • Acts as an abrasive in precision polishing of metals, semiconductors, and optics.
• Composites:
  • Reinforces polymer or metal composites to improve mechanical and thermal properties.
• Electronics:
  • As an insulating material or filler in high-performance electronic components.
• Catalysts:
  • Provides a high-surface-area support for catalytic reactions.
• Thermal Management:
  • Used in heat sinks, thermal interface materials, or other cooling applications.

4. Advantages:

• Uniform Dispersion:
  • Ready-to-use and eliminates the need for additional dispersion steps.
• High Purity:
  • Ensures consistent performance in demanding applications.
• Nano-Sized Effects:
  • Enhanced mechanical, thermal, and optical properties compared to larger particles.
• Environmentally Friendly:
  • Water-based dispersion avoids harmful solvents.

5. Handling and Storage:

• Handling:
  • Shake or stir before use to ensure uniform distribution of nanoparticles.
  • Handle with care to avoid inhalation or skin contact.
• Storage:
  • Store in a cool, dry place, away from direct sunlight.
  • Prevent freezing or overheating to maintain dispersion stability.
