Description

Barium Ferrite Nanopowder is a high-performance magnetic ceramic material composed of barium hexaferrite (BaFe12O19) in a nanoscale particulate form. Its unique combination of high coercivity, excellent chemical stability, and permanent magnetic properties makes it a critical advanced material for modern electronics and industrial applications. This nanopowder is essential for manufacturers and R&D teams in the electronics, data storage, telecommunications, and automotive sectors seeking to miniaturize components and enhance magnetic performance.

Application

• Permanent Magnets: A key raw material for manufacturing sintered and bonded permanent magnets used in motors, sensors, and loudspeakers.
• Magnetic Recording Media: Used in the production of high-density magnetic tapes, floppy disks, and credit card stripes.
• Microwave Devices & Absorbers: Employed in non-reciprocal devices like circulators and isolators, and as radar-absorbing materials (RAM) for stealth technology.
• Ferrofluids & Magnetorheological Fluids: Serves as the magnetic particle component in smart fluids for sealing, damping, and polishing applications.
• Biomedical Applications: Utilized in magnetic hyperthermia for cancer treatment, magnetic separation, and as a contrast agent in magnetic resonance imaging (MRI).
• Catalysis & Environmental Remediation: Acts as a magnetically separable catalyst or adsorbent for wastewater treatment and chemical processes.
• Security & Authentication: Incorporated into inks and pigments for anti-counterfeiting measures on banknotes and documents.
• Electromagnetic Interference (EMI) Shielding: Integrated into composites and coatings to protect electronic devices from EMI.

Quality Control

Our Barium Ferrite Nanopowder is manufactured under a stringent quality management system. Each batch is characterized for critical parameters including particle size distribution (via DLS or SEM), phase purity (via XRD), magnetic properties (coercivity, saturation magnetization), and chemical composition. Certificates of Analysis (COA) detailing these specifications are provided to ensure compliance with your technical requirements and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture absorption and potential agglomeration. Keep away from strong magnetic fields during storage.
