Application

1: Magnetite is a commonly used magnetic material. 

2: A specially made purified magnetite oxide used as raw material for tapes and telecommunication equipment. 

3: Natural magnetite is the raw material for iron making. 

4: Used in making primers and finishes. 

5: Magnetite is the main raw material for the production of iron catalysts (a catalyst). 

It's hard enough to make abrasives. Has been widely used in the field of automotive brake, such as brake pads, brake shoes and so on. 

6: Magnetite has been recognized in the field of welding materials in China, and it is still in the initial stage for the production of welding electrodes and welding wires. The market prospect is very wide. 

7: Fe3O4 has shown good performance in sewage treatment because of its large ratio and strong magnetic properties. 

8: Fe3O4 can also be used as pigments and polishes. 

9: We can also through some chemical reactions, such as the use of sodium nitrite and so on, so that the steel surface to form a layer of dense oxide, used to prevent or slow down the corrosion of the steel surface, such as firearms, saw blade and other blue, black. Commonly known as "blue". 

10: Make special electrode.
