500nm Superfine CAS 1309-37-1 Magnetic Black Iron Oxide Powder Price Nano Fe3O4 Powder

Nature of Nano Fe3O4 Powder:

Iron tetroxide is an inorganic substance with the chemical formula of Fe3O4. It is a black crystal with magnetism, so it is also called magnetic iron oxide. It cannot be regarded as "ferrous metaferrite" [Fe (FeO2) 2], nor can it be regarded as a mixture of ferrous oxide (FeO) and iron oxide (Fe2O3), but it can be approximately regarded as a compound of ferrous oxide and iron oxide (FeO · Fe2O3). This substance is insoluble in water, alkali solution, ethanol, ether and other organic solvents. The natural ferric oxide is insoluble in acid solution, and it is easy to oxidize into iron oxide (Fe2O3) in the air under wet conditions. It is usually used as a pigment and polishing agent, and can also be used to manufacture audio tapes and telecommunications equipment.

1.Fe3O4 also known as , black powder. Density 5.18, the temperature 1538 ° C, while decomposition.

2. The humid condition in the air easily oxidized to ferric oxide. Acid soluble and insoluble in water, ethanol and ether. Pigments and scouring agents. Specially designed magnetic iron oxide system can be used tape recordings and telecommunications equipment.

3. Magnetite natural births. From the steam iron or iron oxide heating at 400 ° C using hydrogen derived

Applications of Fe3O4 Powder

1. Nano powder, magnetic, external magnetic field can be directed to move, and magnetic powder in the external alternating electromagnetic field can produce heat stable chemical properties, which uses a wide range.

2. Uses nano powder is quite extensive. In the biomedical field, magnetic nano-materials are widely used as carriers of various anticancer drugs to form magnetically targeted drug delivery systems.

3. Magnetic microspheres magnetic nano material can be widely used in magnetic separation of immune cells, magnetic resonance angiography imaging and so on.

4. Surface modified nano powder, made from magnetic liquid dispersion medium.

5. Using the deep black color and magnetic of Fe3O4 nanoparticles can be made magnetic materials, high gradient magnetic separator, microwave absorbing materials, special coatings and xerographic developer.

6. The nano-magnetic material can be widely used in various types of chemical fiber, plastics, rubber and other products, health care products, health products, excellent add material.

In the modern electrification and information society, magnetic materials are widely used. As a multifunctional magnetic material, Fe3O4 magnetic material has been widely used in tumor treatment, microwave absorption material, catalyst carrier, cell separation, magnetic recording material, magnetic fluid, medicine and other fields. This material has a bright future.
