Iron oxide black, also known as ferric oxide, is an inorganic substance with the chemical formula Fe3O4, a black crystal with magnetic properties, which is insoluble in water, alkaline solutions and organic solvents such as ethanol and ether. Natural ferric tetroxide is insoluble in acid solutions and is easily oxidized to iron oxide (Fe2O3) in the air in a humid state. It is usually used as pigment and polishing agent, and also used in the manufacture of recording tapes and telecommunication equipment.
Applications
1. ferric tetroxide is a common magnetic material.
2. Specially prepared pure ferric tetroxide is used as a raw material for audio cassettes and telecommunication equipment.
3. Natural magnetite is the raw material for iron making.
4. iron oxide black can be used to make primer and topcoat. 5.
5. ferric oxide is the main raw material for the production of iron catalyst (a catalyst). 6.
6. Iron oxide black is very hard and can be used as abrasive. It has been widely used in the field of automobile braking, such as: brake pads, brake shoes, etc.
7. ferric oxide has been recognized in the field of welding materials, used in the production of electrodes and welding wire is still in its infancy, and the market prospect is very wide.
8. ferric tetroxide has shown good performance in sewage treatment because of its large specific gravity and strong magnetic properties.
9. ferric tetroxide can also be used as pigment and polishing agent.
