What is Fe3O4 powder? Fe3O4 powder is a kind of inorganic chemical formula for Fe3O4. It is commonly known as iron oxide black, magnet, black iron oxide, with magnetic black crystal, so it is also called a magnetic oxidation body. It can not be regarded as "ferrous ferrolate" [Fe (FeO2) 2], nor as a mixture of iron oxide (FeO) and iron oxide (Fe2O3). Still, it can be regarded as a compound of iron oxide and iron oxide (FeO· Fe2O3). This substance is insoluble in water, alkali solution, ethanol, ether, and other organic solvents. Natural ferric oxide is insoluble in acid solution and easily oxidizes to iron oxide (Fe2O3) in the air in a humid state. Usually used as pigments and polishing agents, it can also be used to make recording tapes and telecommunications equipment. Its physical properties are: black Fe3O4 is a mixed valence oxide of iron, melting point of 1594℃ [3], a density of 5.18 g/cm3, water, insoluble, soluble in acid solution, in the form of magnetite in nature, strong sub magnet and high conductivity; chemical properties are: Fe3O4 corrosion effect, such as steel manufacturing blue (also known as burning blue and baking blue) is the oxidation effect of alkaline oxidation solution, steel manufacturing surface form a blue-black or dark blue Fe3O4 film, to increase corrosion resistance, luster, and beauty.
Main uses of Fe3O4powder Fe3O4 powder Is a commonly used magnetic material. Special pure Fe3O4 powder is used as raw materials for audio tapes and telecommunications equipment. Natural magnetite is the raw material for iron-making. It can also be used for making primer and paint. Fe3O4 powder Is the main raw material for the production of iron catalyst (a catalyst). Because of its great hardness, it can be used as an abrasive. Has been widely used in the field of automotive braking, such as: brake pads, brake hooves, etc. Fe3O4 powder In the domestic field of welding materials has been recognized, used for the production of electric welding rod, welding wire is still in the initial stage, the market prospect is ten broad. Fe3O4 powder Because of its significant ratio, strong magnetic characteristics, in the sewage treatment has shown a good performance. Fe3O4 powder It can also be used as a pigment and a polishing agent. We can also through some chemical reactions, such as the use of sodium nitrite and so on, so that the steel surface generated a layer of dense Fe3O4 powder, used to prevent or slow the corrosion of steel, such as guns, saw saw and other surface blue, black. Commonly known as "baked blue". Finally, the Fe3O4 powder also makes special electrodes.
Price of Fe3O4powder The different price of Fe3O4powder purity is also different. The market price of Fe3O4powder is in the process of dynamic change. The price of Fe3O4powder can be found on our company's official website. If you need it, you can ask us at any time.
