    • Iron Oxide Nanopowder

     

    MK Nano provides high-purity iron oxide powder that is perfect for research and industrial usage. We have a lot of different phases in our inventory, such as Fe₂O₃ and Fe₃O₄, with regulated particle sizes and very strong magnetic properties.

    Iron Oxide Nanopowder: Product Details

    Because of their unique superparamagnetic qualities, biocompatibility, and catalytic activity, iron oxide nanoparticles are among the most useful and widely researched nanomaterials. This flexibility comes from the fact that there are many phases and types accessible, each with its own set of properties that make it useful for specific uses. The small size of the nanoparticles gives them a huge surface area, which makes them more reactive and better at what they do than bulk iron oxide powder.

    Different Phases of Iron Oxide Nanopowder

    There are many crystalline forms, or polymorphs, of iron oxide. MK Nano offers the following phases that are most common and essential for businesses:

    • Hematite (α−Fe2​O3​): A reddish-brown phase that is stable at high temperatures and is used in pigments, catalysts, and as an anode material in Li-ion batteries.
    • Maghemite (γ−Fe2​O3​): a brown, ferromagnetic phase that is not stable. It is utilized a lot in biomedical applications and in magnetic recording media.

    Types of Iron Oxide Nanoparticles

    The primary types are based on their chemical formula:

    • Ferric Oxide (Fe2​O3​): Fe2​O3​, or ferric oxide, contains both hematite and maghemite phases.
    • Magnetite (Fe3​O4​): A black, very magnetic substance with significant superparamagnetic qualities that makes it great for MRI contrast agents, ferrofluids, and bioseparation.

    Properties of Iron Oxide Nanoparticles

    We make sure that our iron oxide nanoparticles are very pure and have a consistent morphology. They are very useful in a wide range of fields, from cutting-edge electronics to new medicinal therapies, because of their important physical and chemical features.

    Frequently Asked Questions About Iron Oxide Nanoparticles>

    Q: What is the purpose of iron oxide nanoparticles?

    A: Their main job is to use their magnetic, catalytic, and biocompatible capabilities for things like MRI, medicine delivery, cleaning up the environment, and storing energy.

    Q: What is iron oxide commonly used for?

    A: Iron oxide powder is often used as a pigment in paints and building materials, as a catalyst in chemical processes, and as a crucial ingredient in improved battery anodes and magnetic recording media.

    Q: What is the size range of iron oxide nanoparticles?

    A: They usually vary from 1 to 100 nanometers. MK Nano's products are mostly in the 20 nm to 30 nm range, which is the best region for performance and reactivity.

    Q: What is the absorption peak of iron oxide nanoparticles?

    A: The UV-Visible absorption peak for Fe₂O₃ nanoparticles in a solvent is usually between 350 and 450 nm; however, it may change depending on the size and type of particle.

    Q: What are the different types of iron oxide nanoparticles?

    A: The two primary forms are ferric oxide (Fe₂O₃), which contains hematite and maghemite phases, and magnetite (Fe₃O₄), which is recognized for being very magnetic.

    Q: Does iron oxide powder dissolve in water?

    A: No, iron oxide powder does not dissolve in water. But nanoparticles may form stable colloidal dispersions (suspensions) in water, particularly when their surfaces are functionalized.

    Q: Do iron oxide nanoparticles have significant antibacterial properties?

    A: Yes, they can kill bacteria by creating reactive oxygen species (ROS) that may damage the membranes of bacterial cells. This makes them valuable in certain medical and cleaning situations.

    Q: How are iron oxide nanoparticles made?

    A: Chemical co-precipitation, sol-gel processes, hydrothermal synthesis, and thermal breakdown are all common ways to make materials that let you regulate the size and shape of the particles quite precisely.
