Abstract :
Effects of nanocrystalline ferrite particles
addition on densification behavior and magnetic properties
of the NiCuZn ferrites were investigated. It was
confirmed that nanocrystalline ferrite particles enhanced
densification of the samples obviously. The
reason was attributed to the nanocrystalline particles,
which spread around the micron-sized ferrite particles,
increased contacting area and inter-diffusion of the
particles. When the amount of nanocrystalline particles
addition reached to 30 wt%, the samples obtained an
approximate densification behavior as the 1.5 wt%
Bi2O3 added samples. Due to relatively bigger grain
size, higher sintering density and no different chemical
composition sintering aids added, the sample with
30wt% nanocrystalline ferrite particles got the highest
permeability and relatively high Q-factor when sintered
at 900.
