Titanium Oxide Nanopowder Water Dispersion (TiO2, Rutile, 40wt%, 30nm)

Titanium Oxide Nanopowder Water Dispersion (TiO₂, Rutile, 40 wt%, 30 nm) is a concentrated aqueous suspension of titanium dioxide nanoparticles in the rutile crystalline form. Here’s a detailed explanation:

1. Composition:

• Titanium Dioxide (TiO₂):
  • A widely used material known for its optical, chemical, and thermal stability properties.
• Rutile Phase:
  • The rutile crystalline structure offers:
    • High refractive index for light-scattering applications.
    • Exceptional thermal and chemical stability.
    • Reduced photocatalytic activity compared to anatase, making it ideal for applications requiring durability.
• Nanoparticles (30 nm):
  • The average particle size is 30 nanometers, providing a high surface area for improved performance.
• 40 wt%:
  • The dispersion contains 40% by weight of TiO₂ nanoparticles, offering a concentrated formulation with reduced water content.
• Water-Based Dispersion:
  • The nanoparticles are uniformly dispersed in water, ensuring easy handling and application.

2. Key Properties:

• High Refractive Index:
  • Excellent for UV protection, optical enhancement, and light-scattering applications.
• Thermal Stability:
  • Withstands high temperatures without phase change, ensuring long-term performance.
• Hydrophilic Surface:
  • Compatible with water-based systems and formulations.
• Concentrated Formulation:
  • The 40 wt% concentration minimizes the amount of water, making it suitable for high-load applications.
• Low Photocatalytic Activity:
  • The rutile phase reduces undesired oxidative reactions, enhancing durability.
• Particle Uniformity:
  • Nanoparticles are evenly dispersed, preventing aggregation and ensuring consistent performance.

3. Applications:

• UV Protection:
  • Used in sunscreens, cosmetics, and coatings to block harmful UV rays.
• Coatings:
  • Enhances weather resistance, durability, and UV protection in architectural, automotive, and industrial coatings.
• Pigments:
  • Provides whiteness, opacity, and brightness in paints, inks, and plastics.
• Photocatalysis:
  • Effective in air and water purification systems, though less active than anatase-based TiO₂.
• Composites:
  • Improves mechanical strength, thermal stability, and optical properties in polymer and ceramic composites.
• Energy Applications:
  • Used in solar cells, photocatalytic reactors, and other energy-related technologies.
• Electronics:
  • Functions as a dielectric material in electronic devices and optical layers in sensors.

4. Advantages:

• High Concentration:
  • The 40 wt% dispersion offers more active material for high-efficiency applications.
• Rutile Stability:
  • Ensures durability under UV and high-temperature conditions.
• Versatility:
  • Suitable for a wide range of industrial, environmental, and cosmetic applications.
• Environmentally Friendly:
  • Water-based dispersion avoids hazardous organic solvents.
• Ease of Use:
  • Pre-dispersed and ready for immediate integration into various formulations.

5. Handling and Storage:

• Handling:
  • Shake or stir thoroughly before use to ensure uniform nanoparticle distribution.
  • Use protective gear (gloves, goggles) to avoid direct contact with the concentrated dispersion.
• Storage:
  • Store in a cool, dry environment, away from direct sunlight and temperature extremes.
  • Avoid freezing or prolonged exposure to high temperatures to maintain dispersion stability.
• Safety:
  • While TiO₂ is generally safe, avoid inhalation of mist or prolonged skin and eye exposure.
