This study was undertaken to obtain nanoparticulate CuNiZn ferrite powder by high-energy milling, as this is an approach that could potentially be scaled up for industrial use. Such nanometric particles may be expected to yield sintered ferrites with enhanced properties. The study was conducted using commercial pellets of CuNiZn ferrite powder as raw material. This was subjected to high-energy milling, producing ferrite nanoparticles with an average particle size of ~20 nm. These nanoparticles were then used to form test pieces that were sintered at 1100°C for 5 h, yielding high-density (96%) CuNiZn ferrite ceramics.
