manufacturing process of magnetite powder

Magnetite Black Oxide | General Application | African ...

The ground magnetite powder is partially reduced, releasing some of the oxygen and leaving behind a magnetite core with an iron shell. This process, which is known as the Haber-Bosch or H-B process, gives the magnetite a highly-porous and greatly increased surface area, which makes it highly active.

Magnet Manufacturing Process | How Are Magnets

Magnet Manufacturing Process. There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via “liquid phase sintering”. Therefore, these magnets are most often called sintered magnets.

Magnet - Powder magnets | Britannica

Magnet - Magnet - Powder magnets: The problem of producing magnets composed of compacted powders is essentially that of controlling particle sizes so that they are small enough to comprise a single domain and yet not so small as to lose their ferromagnetic properties altogether. The advantage of such magnets is that they can readily be molded and machined into desired shapes.

What is Powder Metallurgy - A Modern

In the powder compacting, a high pressure is applied to compact a metal powder in a die. In this process, as high pressure is applied to the powder, the density of the powder changes. The common pressure of 0.5 MPa to 7 MPa is maintained during this process. For metal powder compaction, the pressure ranges from 150 MPa to 700 MPa.
