This product is prepared by liquid phase precipitation method combined with high-temperature calcination process, with an iron oxide purity of up to 99.5%. The impurity content is strictly controlled at a very low level, SiO2≤0.02%, Al2O3≤0.01%, effectively avoiding the negative impact of impurities on the magnetic performance of magnetic materials. Its ultra-fine and uniform particle size (0.1-0.3μm) and appropriate specific surface area (8.5m²/g) make the magnetic powder have excellent dispersibility and forming density during the forming process, improving the remanence and coercivity of permanent magnets. At the same time, the extremely low moisture content (≤0.05%) avoids the agglomeration of magnetic powder during the mixing process, adapting to large-scale automated magnetic material production processes.
Iron oxide content ≥99.5%, particle size range 0.1-0.3μm, specific surface area 8.0-9.0 m²/g, tap density 1.1-1.3 g/cm³, moisture content ≤0.06%, impurity content (SiO2≤0.02%, Al2O3≤0.01%, CaO≤0.01%), pH value 7.0±0.5, packaged in 5kg moisture-proof aluminum foil bags with Pallets, compliant with industrial dangerous goods transportation standards, passed ISO/TS 16949 automotive grade quality certification.
It is mainly used in the production of strontium ferrite permanent magnet materials, soft magnetic cores, motor magnetic tiles, automotive permanent magnet components and other high-end magnetic components, adapting to scenarios such as new energy vehicle motors, household appliance permanent magnet components, industrial magnetic separation equipment, etc. It can improve the consistency of magnetic performance and product yield of magnetic materials, and is especially suitable for high-end magnetic material manufacturing enterprises with extremely high magnetic performance requirements.
