Fe2O3 Iron Oxide Nanopowder Water Dispersion (Gamma, 99.9%, 20nm, 10wt%)

Fe₂O₃ Iron Oxide Nanopowder Water Dispersion (Gamma, 99.9%, 20 nm, 10 wt%) is a water-based suspension containing high-purity gamma-phase iron oxide (Fe₂O₃) nanoparticles with a 20 nm particle size and a concentration of 10% by weight. Here’s a detailed breakdown of this material:

1. Composition:

• Iron Oxide (Fe₂O₃):
  • The Fe₂O₃ nanoparticles are made of iron oxide, which is a compound of iron and oxygen. It is used widely for its magnetic properties, chemical stability, and catalytic behavior. In this case, it is the gamma-phase (γ-Fe₂O₃), also known as maghemite, which has distinct properties compared to other phases like hematite or magnetite.
• Gamma-Phase (γ-Fe₂O₃):
  • The gamma-phase (γ-Fe₂O₃), or maghemite, is a metastable form of iron oxide that is often used in magnetic applications due to its high magnetic susceptibility. It is commonly found in various industrial and environmental applications.
• Purity (99.9%):
  • The 99.9% purity indicates that the nanopowder is of very high quality, with minimal impurities. This ensures that the product will perform consistently and reliably in demanding applications.
• Particle Size (20 nm):
  • The 20 nm particle size provides a good balance between surface area and stability. These nanoparticles have a moderate surface area, which is ideal for various applications like catalysis and sensors, where both reactivity and stability are important.
• Concentration (10 wt%):
  • The 10% by weight concentration means that 10% of the dispersion is made up of iron oxide nanoparticles, while the rest is water. This is a lower concentration compared to some other dispersions, but it is still suitable for applications where moderate nanoparticle content is needed.

2. Key Properties:

• Moderate Surface Area:
  • The 20 nm particle size provides a relatively high surface area compared to larger nanoparticles, but not as high as finer particles. This makes it effective for applications that require a balance between surface area and physical stability.
• Magnetic Properties:
  • Gamma-Fe₂O₃ (maghemite) has strong magnetic properties, making it useful for applications in magnetic storage, sensors, and other devices requiring magnetic behavior. It can also be used in ferrofluids, where its magnetic nature allows it to be controlled by external magnetic fields.
• Chemical and Thermal Stability:
  • Gamma-Fe₂O₃ is stable under a range of chemical conditions and can handle moderate temperatures without significant degradation. It has good resistance to oxidation, which is important for long-term stability in various industrial and environmental applications.
• Water-Based Dispersion:
  • This product is water-based, meaning it is easier and safer to handle than solvent-based dispersions. It is also more environmentally friendly and can be integrated into water-based industrial processes.

3. Applications:

• Catalysis:
  • The 20 nm gamma-Fe₂O₃ nanoparticles are suitable for use in catalytic processes due to their moderate surface area and high reactivity. They can be used as catalysts or catalyst supports in various chemical reactions, including oxidation reactions.
• Magnetic Materials:
  • Gamma-Fe₂O₃ nanoparticles are used in magnetic materials, such as in magnetic storage devices, magnetic sensors, and ferrofluids. The magnetic properties of these nanoparticles make them ideal for such applications.
• Sensors:
  • The 20 nm size and magnetic properties make gamma-Fe₂O₃ nanoparticles suitable for sensors, particularly magnetic sensors or those that rely on changes in the magnetic properties of the material.
• Environmental Remediation:
  • Iron oxide nanoparticles are also used for environmental applications, including the removal of pollutants from water. Their high surface area enables them to adsorb contaminants effectively, and the gamma-phase gives them additional stability during these processes.
• Pigments and Coatings:
  • Gamma-Fe₂O₃ nanoparticles can be used in pigments and coatings, providing color as well as potential magnetic functionality. They are also utilized in products requiring magnetic properties in coatings for various industrial uses.
• Energy Storage:
  • Iron oxide nanoparticles, particularly gamma-Fe₂O₃, are being investigated for use in energy storage devices like supercapacitors or batteries. Their conductivity and magnetic properties may be beneficial in improving the performance of these devices.
• Biomedical Applications:
  • Gamma-Fe₂O₃ is also used in biomedical applications, including magnetic resonance imaging (MRI), drug delivery, and targeted therapies due to its magnetic properties, biocompatibility, and ability to be manipulated by external magnetic fields.

4. Advantages:

• High Purity (99.9%):
  • The 99.9% purity ensures minimal contamination, improving the reliability and consistency of the material in sensitive applications such as catalysis and biomedical uses.
• Magnetic Properties:
  • The magnetic properties of gamma-Fe₂O₃ are advantageous in applications like magnetic sensors, magnetic data storage, and ferrofluids.
• Moderate Surface Area:
  • The 20 nm particle size provides a balance of surface area and stability, making it suitable for a variety of applications, including catalysis, sensors, and coatings.
• Water-Based Dispersion:
  • The water-based nature makes the material safer to handle, environmentally friendly, and easier to integrate into water-based processes compared to solvent-based systems.

5. Handling and Storage:

• Handling:
  • Always shake or stir the dispersion well before use to ensure uniform distribution of the nanoparticles. Personal protective equipment (PPE), such as gloves and goggles, should be worn to avoid direct contact with the dispersion.
• Storage:
  • Store the dispersion in a cool, dry place, away from direct sunlight and high temperatures. Ensure that the container is properly sealed to prevent water evaporation and changes in concentration.
• Safety:
  • While Fe₂O₃ is generally considered safe, nanoparticles should be handled with care to prevent inhalation or contact with skin or eyes. Work in a well-ventilated area to avoid inhaling fine particles.
