Titanium Oxide Nanopowder Water Dispersion (TiO2, Rutile, 20 wt%, 30-50 nm)

Titanium Oxide Nanopowder Water Dispersion (TiO₂, Rutile, 20 wt%, 30–50 nm) is a water-based suspension of titanium dioxide nanoparticles in the rutile crystalline phase. Here’s an overview of its composition, properties, and applications:

1. Composition:

• Titanium Dioxide (TiO₂):
  • A high-performance material widely used in coatings, pigments, and functional applications.
• Rutile Phase:
  • The rutile crystalline form is:
    • Known for its high refractive index.
    • Chemically and thermally stable.
    • Less photocatalytically active than anatase, which reduces oxidative degradation in sensitive applications.
• Nanoparticles (30–50 nm):
  • The particle size range of 30–50 nanometers provides excellent light-scattering and stability characteristics.
• 20 wt%:
  • Contains 20% by weight of TiO₂ nanoparticles suspended in water, with the remaining 80% being the dispersion medium.
• Water-Based Dispersion:
  • Ensures easy handling and compatibility with aqueous systems.

2. Key Properties:

• High Refractive Index:
  • Ideal for UV shielding and enhancing optical properties.
• Thermal Stability:
  • Withstands high temperatures, maintaining its phase integrity.
• Lower Photocatalytic Activity:
  • Rutile TiO₂ is less reactive than anatase, making it more durable in coatings and composites.
• Stable Dispersion:
  • Nanoparticles are uniformly suspended to prevent settling or agglomeration.
• Hydrophilic Surface:
  • Easily integrates into water-based systems.
• Particle Size:
  • The 30–50 nm size range offers a balance between surface activity and mechanical stability.

3. Applications:

• UV Protection:
  • Used in sunscreens, cosmetics, and protective coatings for outdoor surfaces.
• Coatings:
  • Enhances durability, weather resistance, and UV blocking in architectural, automotive, and industrial coatings.
• Pigments:
  • Provides opacity and whiteness in paints, inks, plastics, and ceramics.
• Photocatalysis:
  • Suitable for air and water purification applications with moderate photocatalytic activity.
• Energy Applications:
  • Used in solar cells, photocatalytic reactors, and energy storage systems.
• Composite Materials:
  • Reinforces mechanical strength, thermal stability, and UV resistance in polymers and ceramics.
• Electronics:
  • Functions as a dielectric material and optical layer in electronic devices and sensors.

4. Advantages:

• High Stability:
  • The rutile phase ensures long-term durability under UV exposure and high temperatures.
• Versatility:
  • Compatible with various industrial, cosmetic, and environmental applications.
• Pre-Dispersed:
  • Ready-to-use water-based formulation simplifies handling and application.
• Environmentally Friendly:
  • Avoids the use of organic solvents, reducing environmental and health risks.

5. Handling and Storage:

• Handling:
  • Shake or stir well before use to ensure uniform nanoparticle distribution.
  • Use appropriate protective equipment, such as gloves and goggles, to avoid direct contact.
• Storage:
  • Store in a cool, dry location, away from direct sunlight and extreme temperatures.
  • Prevent freezing or overheating, as this may destabilize the dispersion.
• Safety:
  • TiO₂ is generally safe but avoid inhalation of mist or prolonged skin exposure to the dispersion.
