| Name | Magnetic powder |
| Synonyms | Magnetic powder |
| Molecular Formula | γ-Fe2O3 |
| Physical and Chemical Properties | Properties Magnetic powder is the core component of magnetic coatings and is the main factor that determines the magnetic properties of magnetic recording media. It should have enough coercivity to effectively improve the demagnetization, but not to the extent that it is difficult to demagnetize. Its magnetization should be of the same order of magnitude as ferromagnetic metal to provide sufficient magnetic flux to the magnetic head; The particles should be uniform, no sintered blocks, and the crystallization is complete. |
| Use | Uses for coating all kinds of audio tape, video tape, measuring tape, instrument special tape and magnetic drum, disk and other storage components |
introduction
Magnetic powder, a hard magnetic single domain particle. It is made of magnetic paste with adhesives, solvents, etc., and coated on the surface of plastic or metal substrate (support) to make magnetic recording materials such as magnetic tapes, disks, and magnetic cards. Magnetic powder is the core component of magnetic coatings and is the main factor that determines the magnetic properties of magnetic recording media.
application
magnetic powder is mainly used for coating various audio tapes, video tapes, measuring tapes, special tapes for instruments, magnetic drums, magnetic disks and other storage components.
