Product Description

Barium Ferrite Powder offered by us is used in the recording medium, permanent magnets, and magnetic stripe cards, among other things. Because of the materials stability, it may be considerably decreased in size, resulting in a much higher packing density. This powder is very effective and safe to use. This inorganic chemical compound is made up of iron oxides that have been sintered with Barium and Strontium carbonates at high temperatures. This powder is very economical and widely appreciated in the market.

Barium Ferrite Powder Applications:

Barium ferrite powder, also known as barium hexaferrite or BaFe₁₂O₁₉, is a type of ceramic material that exhibits strong magnetic properties. It is commonly used in various applications where high coercivity and magnetic stability are required. Here are some of the main applications of barium ferrite powder:

1. Magnetic Recording Media: Barium ferrite powder is widely used in the production of magnetic recording media, such as hard disk drives (HDDs), floppy disks, and magnetic tapes. It is used as the magnetic material in the thin films or coatings that store and retrieve data magnetically.

2. Permanent Magnets: Due to its strong magnetic properties, barium ferrite powder is employed in the production of permanent magnets. These magnets find applications in various industries, including automotive, aerospace, electronics, and medical. Barium ferrite magnets are known for their high coercivity, which makes them suitable for applications requiring stable and strong magnetic fields.

3. Microwave Devices: Barium ferrite powder is utilized in the manufacturing of microwave devices, such as circulators, isolators, and phase shifters. These devices rely on the magnetic properties of barium ferrite to control the propagation of microwave signals.

4. Magnetic Sensors: Barium ferrite powder can be used to produce magnetic sensors, such as magnetoresistive sensors and magnetic field sensors. These sensors are used in a range of applications, including position sensing, motion detection, and current sensing.

5. Electromagnetic Filters: Barium ferrite powder is employed in the fabrication of electromagnetic filters and absorbers. These devices are used to control and suppress unwanted electromagnetic interference (EMI) in electronic circuits and systems.

6. Magnetic Fluids: Barium ferrite powder can be dispersed in a carrier liquid to create magnetic fluids or ferrofluids. These fluids exhibit unique properties and are used in applications like sealing, damping, and heat transfer, particularly in areas where precise control of magnetic fields is required.

7. Catalyst Supports: Barium ferrite powder can serve as a catalyst support in various chemical processes. Its high surface area and chemical stability make it suitable for applications such as catalytic converters and exhaust gas treatment.

Barium Ferrite Powder Properites:

Barium ferrite powder, also known as barium hexaferrite or BaFe₁₂O₁₉, possesses several key properties that make it useful in various applications. Here are the main properties of barium ferrite powder:

1. Magnetic Properties: Barium ferrite powder exhibits high magnetization and coercivity, making it a strong permanent magnet material. It has a high saturation magnetization, which means it can be magnetized to a high degree and generate a strong magnetic field. Its high coercivity ensures that the magnetization remains stable over time.

2. Chemical Stability: Barium ferrite powder is chemically stable, which allows it to resist corrosion and degradation when exposed to environmental conditions. This stability is essential for applications where the material needs to maintain its magnetic properties over extended periods.

3. Anisotropy: Barium ferrite powder is anisotropic, meaning its magnetic properties vary with the direction of magnetization. This anisotropy is due to the crystal structure of barium ferrite, which results in preferential alignment of magnetic domains. It allows for the control and manipulation of magnetic fields in specific directions.

4. High Curie Temperature: The Curie temperature of barium ferrite powder is relatively high, typically around 450-460 degree centigrade. The Curie temperature is the temperature at which a material loses its ferromagnetic properties. The high Curie temperature of barium ferrite makes it suitable for applications that require operation at elevated temperatures.

5. Insulating Properties: Barium ferrite is an electrical insulator, which means it does not conduct electricity. This property is advantageous in applications where electrical isolation is necessary, such as in magnetic sensors and microwave devices.

6. High Hardness: Barium ferrite powder is a hard material, which contributes to its durability and resistance to wear. This property is important in applications where the material may be subjected to mechanical stress or abrasion.

7. Low Density: Barium ferrite has a relatively low density, which makes it lightweight compared to some other magnetic materials. This characteristic is beneficial for applications where weight reduction is desired, such as in portable electronics or automotive components.

8. Low Cost: Barium ferrite powder is generally more cost-effective compared to some other magnetic materials like rare-earth magnets. Its availability and relatively low cost make it a viable option for a wide range of applications.
