Titanium Oxide Nanopowder Water Dispersion (TiO2, Rutile, 15 wt%, 5-30 nm)

Titanium Oxide Nanopowder Water Dispersion (TiO₂, Rutile, 15 wt%, 5–30 nm) is a water-based suspension of titanium dioxide nanoparticles in the rutile crystalline form. Below is a detailed explanation of its composition, properties, and applications:

1. Composition:

• Titanium Dioxide (TiO₂):
  • A widely used metal oxide with applications in coatings, pigments, and photocatalysis.
• Rutile Phase:
  • The rutile phase of TiO₂ is characterized by:
    • Higher refractive index compared to anatase.
    • Excellent thermal and chemical stability.
    • Lower photocatalytic activity, making it ideal for durable applications.
• Nanoparticles (5–30 nm):
  • Ultra-fine particles with an average size range of 5 to 30 nanometers.
  • Nano size ensures enhanced optical and reactive properties.
• 15 wt%:
  • 15% by weight of the dispersion consists of TiO₂ nanoparticles; the remaining 85% is water.
• Water Dispersion:
  • Aqueous medium that ensures even particle distribution, making it ready-to-use for various applications.

2. Key Properties:

• High Refractive Index:
  • Provides exceptional light scattering, making it ideal for UV shielding and optical enhancement.
• Thermal Stability:
  • Withstands high temperatures without decomposition or phase change.
• Hydrophilic Surface:
  • Disperses easily in water-based systems.
• Low Photocatalytic Activity:
  • The rutile form minimizes oxidative degradation, making it safer for coatings and cosmetics.
• Uniform Dispersion:
  • Maintains a stable and even distribution of nanoparticles in water.
• Durability:
  • Resistant to chemical and environmental degradation, making it suitable for outdoor and industrial applications.

3. Applications:

• UV-Resistant Coatings:
  • Used in transparent and durable coatings for buildings, automotive, and outdoor structures.
• Sunscreens and Cosmetics:
  • Provides effective UV protection with a non-reactive and safe formulation.
• Optical Materials:
  • Enhances brightness and opacity in paints, plastics, and textiles.
• Pigments:
  • Adds whiteness and opacity to a variety of products such as paints, inks, and ceramics.
• Photocatalysis:
  • Applicable in self-cleaning materials, air purification, and water treatment systems.
• Composite Materials:
  • Enhances mechanical strength and thermal resistance in polymers, ceramics, and metals.
• Energy Applications:
  • Used in dye-sensitized solar cells (DSSCs) and other photovoltaic systems.
• Electronics:
  • Serves as a dielectric material and optical layer in microelectronics and sensors.

4. Advantages:

• Pre-Dispersed:
  • Ready-to-use formulation saves preparation time and ensures uniform application.
• Environmentally Friendly:
  • Water-based formulation avoids the use of harmful organic solvents.
• Enhanced Performance:
  • Nano-sized particles improve surface interactions, UV protection, and thermal stability.
• Versatile:
  • Suitable for a wide range of industrial, cosmetic, and environmental applications.
• Stable Rutile Phase:
  • Offers longevity and resistance to wear and environmental stress.

5. Handling and Storage:

• Handling:
  • Stir or shake well before use to ensure uniform nanoparticle distribution.
  • Use protective gloves and eyewear to avoid direct contact.
• Storage:
  • Store in a cool, dry place away from direct sunlight and extreme temperatures.
  • Avoid freezing or prolonged exposure to high heat, as these can destabilize the dispersion.
• Safety:
  • While TiO₂ is generally considered non-toxic, avoid inhalation of mist and prolonged exposure to skin and eyes.

This TiO₂ water dispersion combines the stability of the rutile phase with the enhanced properties of nano-sized particles. Its versatility makes it suitable for coatings, cosmetics, composites, and energy applications. The 5–30 nm size range allows for a balance between surface reactivity and stability, making it a valuable material in both industrial and scientific fields.
