PH:6-8

Note: We can supply different size products of Fe3O4 nano magnetic slurry according to client's requirements.

The nanometer ferroferric oxide (Fe3O4) powder is magnetic and can be oriented and moved under an external magnetic field. The particle size has superparamagnetism within a certain range, and can generate heat and other characteristics under the action of an alternating electromagnetic field. Stable performance and therefore versatile.

Application of Fe3O4 nano magnetic slurry:

1. Magnetic seal: Magnetic fluid, also known as magnetic fluid or ferrofluid, has the characteristics of being able to control its physical properties through a magnetic field, and has the fluidity, lubricity and sealing properties of the liquid carrier.
2. Biomedical field: Magnetic microspheres made of magnetic nanometer ferroferric oxide can also be widely used in the separation of magnetic immune cells and nuclear magnetic resonance imaging.
3, magnetic health: water-based magnetic liquid as a similar magnetic pigment can be easily added to a variety of products; can be widely used in various types of chemical fiber, plastics, rubber, etc., is the addition of health care products, health products.
4. Magnetic recording materials, high gradient magnetic separators, microwave absorbing materials, special coatings and xerographic developers can be made by utilizing the magnetic and dark black colors of the nanometer ferroferric oxide powder.

Storage conditions:
Fe3O4 nano magnetic slurry should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
