纳米四氧化三铁

Nano iron trioxide

Product name: Nanometer Fe3O4 Molecular formula: Fe3O4 Relative molecular weight: 231.54

Nano iron trioxide (Fe3O4) powder has a certain degree of magnetism and can move directionally under an external magnetic field. The particle size has superparamagnetism within a certain range, and can generate heat under the action of an external alternating electromagnetic field. Its chemical properties are stable, making it widely used.

Our company produces nano ferric oxide using the best process formula and route, with a simple and safe preparation process, low energy consumption, and maintaining the particle size of magnetic particles at the nanometer level. Through magnetic performance testing, it can be found that the magnetic particles have superparamagnetism, and their technical indicators reach and exceed the performance of magnetic nano ferric oxide at home and abroad, providing a foundation for the application of various magnetic fluids in China.

Product performance and application scenarios:

(1) Magnetic seal:

Used for precision instruments, precision machinery, gas sealing, vacuum sealing, pressure sealing, etc; Dynamic sealing is the most widely used and can achieve zero leakage. It has the advantages of low sealing fluid consumption, shock resistance, no mechanical wear, small friction, low power consumption, no aging, self-lubricating, long service life, wide speed adaptation range, simple structure, low requirements for shaft machining accuracy and smoothness, and reliable sealing.

(2) In the field of biomedicine:

Magnetic nanomaterials are widely used as carriers for various anti-cancer drugs, forming a magnetic targeted drug delivery system; Magnetic microspheres made of magnetic nanomaterials can also be widely used for the separation of magnetic immune cells, magnetic resonance imaging, and other aspects. By utilizing the characteristic of magnetic nanomaterials generating heat under the action of an external alternating electromagnetic field, tumor cells can be killed, achieving the goal of treating tumors.

(3) Magnetic healthcare

It has disease treatment and health benefits for the human body. Based on this principle, we have invented nano magnetic powders, which enable products with added powders to adjust human functions and improve disease resistance, playing a role in healthcare. The water-based magnetic liquid produced has good stability and can be uniformly dispersed even after being left for several months. Therefore, water-based magnetic liquids can be easily added to various products as a type similar to magnetic pigments; It can be widely used in various types of chemical fibers, plastics, rubber, etc., and is an excellent additive material for health products and wellness products.

(4) By utilizing the magnetic properties and dark black color of nano Fe3O4 powder, magnetic recording materials, high gradient magnetic separators, microwave absorbing materials, special coatings, and electrostatic copying developers can be made.
