PURPOSE:To provide an industrial production process for a soft ferrite particle for low-temperature sintering to give a sintered ferrite having high magnetic permeability in the frequency range of 1-MHz to 100MHz even by sintering at a low temperature, i.e., <=900 deg.C. CONSTITUTION:Ni-Zn-Cu soft ferrite particle powder for low-temperature sintering is produced by using gamma-Fe2O3 powder having an average particle diameter of <=0.06mum as the Fe2O3 raw material, calcining the raw material powder in a range of 750-800 deg.C and roughly crushing the calcined product. |
