AI Technical Summary
Existing processes for preparing planar hexagonal ferrites mostly employ rotating magnetic field orientation technology, which involves complex equipment, makes it difficult to achieve industrial-scale production, and results in high costs and low efficiency.
Uniaxial Cu-18H hexagonal ferrite was synthesized via solid-state reaction using uniaxial magnetic field orientation technology and Ni2+ ion substitution control technology. The uniaxial magnetic field was used to make the grains uniformly aligned in space, and planar CuNi-18H hexagonal ferrite was generated under high-temperature sintering.
A high-orientation, low-cost, and high-efficiency production of high-frequency soft magnetic materials has been achieved. Ba5Cu2Ti3Fe12O31 ferrite with high permeability, high natural resonance frequency, and low magnetic loss is suitable for large-scale industrial production.
