Barium Ferrite Micro Powder (BaFe2O4, Purity: 99.9%, APS: 60-70µm)

Barium Ferrite Micro Powder

Introduction

Barium ferrite  BaFe2O4 micro powder is a type of ferrite material that is composed primarily of barium and iron. It is a ceramic compound known for its unique magnetic properties, particularly its high magnetic coercivity, which allows it to retain magnetism even when external magnetic fields are removed. Barium ferrite micro powder is produced by grinding the ferrite material into very fine particles (micron-sized), which enhances its surface area and reactivity.

This material is a type of permanent magnet that is chemically stable, non-toxic, and has excellent corrosion resistance. Due to its fine particle size, it exhibits enhanced magnetic performance, making it suitable for a wide range of applications.

Applications

Data storage devices: Barium ferrite micro powder is commonly used in the production of magnetic tapes and discs for data storage. The high coercivity of barium ferrite allows it to store data for extended periods without loss of information.

Magnetic ink: Used in printing applications, particularly in check processing and security printing.

Permanent Magnets:

Loudspeakers: Barium ferrite is used in the production of high-performance magnets for speakers, especially in compact audio devices where space is limited.

Motors and actuators: Used in small motors, sensors, and actuators, particularly in low-power, high-efficiency applications.

Magnetic separators: The material is used in industrial magnetic separators for separating ferromagnetic particles from non-ferrous materials.

Electromagnetic Shielding:

Due to its excellent magnetic properties, barium ferrite is utilized in electromagnetic shielding applications to protect sensitive electronics from electromagnetic interference (EMI).

Sensors:

Magnetic field sensors: Barium ferrite micro powder is used in the manufacturing of sensors that detect and measure magnetic fields, such as in automotive applications or position sensing in robotics.

Catalysts in Chemical Reactions:

Barium ferrite has been explored as a catalyst for certain chemical reactions, especially in the field of hydrogen production and other energy applications.
