Multi-purpose 99% Fe3O4 Super Fine High Purity Fe Magnetite Iron Powder

Overview of Iron Oxide Fe3O4 Powder      

Iron Oxide Fe3O4 Powder, also referred to as magnetite, is a black, crystalline powder composed of iron and oxygen. It comes from the classification of iron oxides, particularly a mixed-valence substance with both ferrous (Fe2+) and ferric (Fe3+) ions existing. Magnetite is highly magnetic, making it a beneficial product in various markets. It exhibits both ferromagnetic and paramagnetic properties, depending on the particle size and temperature. Its magnetic nature allows it to be used in multiple applications, such as magnetic recording media, magnetic fluids, and magnetic separators. Magnetite powder is also used in the production of pigments, abrasives, and catalysts. Its special physical and chemical properties make it a versatile material with a wide range of applications.

Production Method of Iron Oxide Fe3O4 Powder

• Chemical Coprecipitation Method: In an aqueous solution, ferrous and ferric salts are mixed in a certain proportion and react with an alkali solution. Through precise control of reaction conditions like temperature, pH value and reactant concentration, high-purity Fe₃O₄ powder can be obtained.
• Hydrothermal Method: Ferrous or ferric salts are placed in a sealed hydrothermal reaction kettle, and under high temperature and high pressure conditions, they react with water or other substances in the solution to form Fe₃O₄. The hydrothermal environment can promote the growth and crystallization of the powder, resulting in good crystallinity and controllable particle size.
• Sol-gel Method: Organic or inorganic iron salts are dissolved into a solvent to form a sol, and then through hydrolysis and condensation reactions, it is transformed into a gel. After drying and calcination, Fe₃O₄ powder is obtained. This method can precisely control the composition and structure of the powder.

Storage Condition of Iron Oxide Fe3O4 Powder

Store iron oxide Fe₃O₄ powder in a cool, dry environment, preferably at 15 – 25°C. Humidity should be kept low, as high moisture can lead to oxidation and agglomeration. Use airtight containers to prevent contact with oxygen and moisture in the air, which could degrade the powder over time. Keep it away from strong acids, bases, and reducing agents to avoid chemical reactions. Store in a well – ventilated area, away from direct sunlight, to maintain its stability and quality for various applications such as in magnetic materials, catalysts, and pigments.
