2016 high quality iron oxide black inorganic pigment

Do you want to know what it is?

Fe3O4, chemical formula Fe3O4. Commonly known as the black iron oxide, magnet, magnet, black, black crystals with magnetic properties, so it is also called magnetic iron oxide. Can't read "partial ferrous iron" or "partial acid ferric [Fe (FeO2) 2]", a mixture of iron oxide and not ferrous oxide, but can be considered as the compound ferrous and ferric oxide. This substance dissolved in acid solution, insoluble in water, alkali solution and ethanol, ether and other organic solvents. Natural magnetite is insoluble in acid solution, wet conditions easily in the air oxidation of ferric oxide. Usually used as pigments and polishes, as well as for recording tapes and telecommunications equipment.

Do you want to know the application of it?

Fe3O4 is a commonly used magnetic material.
The raw materials used for special pure Fe3O4 magnetic tape and telecommunications equipment.
Natural magnetite is the raw material for ironmaking.
For primer and finish.
Magnetite is the production of iron catalyst (catalyst) as main raw material.
Its hardness is very large, can be used as abrasive. Has been widely used in the field of automotive braking, such as: brake pads, brake shoes, etc..
Magnetic field of welding materials has been recognized in the country, for welding, welding wire production is still in the initial stage, the market prospect is very broad.
Because of its major characteristics of magnetite, magnetic intensity, in sewage treatment shows good performance.
Can also be used as a polishing agent and ferroferric oxide pigment.
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".
Make special electrode.
