Core Material Classification Technologies
Classification by Magnetic Properties
Soft Magnetic Ferrite Technology: Centered on Mn-Zn and Ni-Zn ferrites, this technology focuses on optimizing formulations for high permeability and low high-frequency loss to meet the requirements of inductive components operating in the 1 kHz–300 MHz frequency range.
Permanent Magnet Ferrite Technology: Centered on barium and strontium ferrites, this technology achieves high coercivity and high remanence by controlling the hexagonal magnetoplumbite crystal structure.
Gyromagnetic/Rectangular-Loop/Piezomagnetic Ferrite Technology:Involves targeted control technologies for microwave gyromagnetic properties, rectangular hysteresis loops, and linear magnetostriction coefficients, respectively, catering to specialized applications such as radar, computer storage, and ultrasonic devices.
Classification by Crystal Structure
Spinel Ferrite Technology:Based on the general formula MFe₂O₄, this is the dominant structural technology for soft magnetic and certain gyromagnetic materials.
Magnetoplumbite Ferrite Technology: Distinguished by high coercivity and chemical stability, this is the core structural technology for permanent magnet materials.
Garnet Ferrite Technology: Exemplified by Yttrium Iron Garnet (YIG), this is a key structural technology in the field of microwave communications.
