Abstract
Microstructures of ferrite obtained with differently processed powders both at various temperatures and times of sintering were examined and growth sequence was observed. Grain growth process is divided into four stages with respect to microstructure and processes occurring in each stage were discussed.
Effects of calcination and ball milling on the grain growth in Mn-Zn ferrite were studied and it is shown that the wide variation obseved in growth behavior could be interpreted in terms of calcination as well as ball-milling performance. Based on these experimental results, mechanism of grain growth is presented.
