• Fine Particle Size (10 nm):
  • The small particle size enhances the reactivity and surface area of the nanoparticles, making them ideal for applications requiring high surface interaction, such as catalysis, energy storage, and sensor development.
• Chemical and Thermal Stability:
  • The alpha-phase iron oxide’s resistance to chemical degradation and its ability to perform in high-temperature conditions make it suitable for use in harsh industrial and environmental applications.
• Magnetic Properties:
  • The magnetic characteristics of Fe₂O₃ nanoparticles make them versatile for applications in data storage, sensors, and other magnetic-based systems.
• Water-Based Dispersion:
  • The water-based nature of the dispersion makes it safer to handle and more environmentally friendly compared to solvent-based dispersions. It is also easier to incorporate into water-based processing and applications.

5. Handling and Storage:

• Handling:
  • Ensure that the dispersion is mixed well before use to maintain even distribution of the nanoparticles. Wear appropriate personal protective equipment (PPE) such as gloves and goggles when handling the dispersion.
• Storage:
  • Store the dispersion in a cool, dry place, away from direct sunlight and excessive heat to prevent the degradation of nanoparticles. Ensure that the container is sealed properly to avoid evaporation of the water.
• Safety:
  • Iron oxide is generally safe to handle, but nanoparticles should be treated with care to avoid inhalation or contact with eyes. Always handle the dispersion in a well-ventilated area.
