Iron Oxide powder is a mixed valence oxide powder with strong magnetic properties, excellent electrical conductivity, insoluble in water but soluble in acids, often black in colour, which has a wide range of applications in magnetic materials, pigments, biomedicine and other fields.
VIMATERIAl offers Iron Oxide powders. Our Iron Oxide powders are characterised by uniform particle size, low impurity content, high chemical stability and good performance in applications. We have a professional technology research and development team, accept custom and experimental, if you need please contact us.
Molecular Formula: Fe₃O₄
Molecular weight: 231.54
Appearance: Usually black powder or black cubic crystal.
Density: about 5.18g/cm³.
Melting point: 1594.5°C
Crystal structure: Inverse spinel type, cubic crystal system, belongs to the inverse spinel structure of ionic crystals, the crystal is composed of O²- containing tetrahedral voids and octahedral voids of the skeleton, Fe²⁺, Fe³⁺ filled in the polyhedral voids formed by O²-.
In the field of magnetic materials: Iron Oxide powders are used for the manufacture of high-performance magnets, magnetic recording media and magnetic sensors thanks to their strong magnetic properties, e.g. magnetic storage layers in computer hard discs.
Biomedical field: It can be used as a drug carrier to achieve magnetic targeting drug delivery, and can also be used for cell and protein separation, magnetic resonance imaging contrast agent, and magnetic heat therapy for tumours.
Catalyst field: It can be used as a catalyst in many chemical reactions, such as organic synthesis reaction, hydrogen precipitation reaction and ozone decomposition reaction, etc. It can reduce the activation energy of the reaction and improve the reaction rate and selectivity.
Electronic device field: used in the manufacture of electronic components, such as transformer cores, inductors, etc., to help improve the performance and miniaturisation of electronic devices.
Each batch of our products starts from the careful selection of raw materials and goes through several advanced processes, with strict parameter control and real-time monitoring at each step. The entire production process follows the international quality management system, and the use of high-precision testing equipment carries out all-around precision testing of particle size distribution, purity, impurity content and other key indicators, without sparing any minor defects, in order to ensure the quality of each batch of products.
Iron Oxide powder is packed in double vacuum bags or bottles and cartons.
Iron Oxide powder should be stored in a dry, cool, well-ventilated environment, sealed packaging, avoid contact with acidic substances, strong oxidants, prevent moisture and redox reactions to ensure the stability of its physical and chemical properties.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
