It has been investigated to densify manganese-zinc ferrite for magnetic heads by the hot isostatic press (HIP) method. The sintering process consists of a conventional presintering and a HIP at high gas pressure. It is necessary for the densification of ferrites by non-encapsulating HIP to make the density of ferrites more than 95% of the theoretical value in presintering process. Ferrites with uniform grain size are obtained by controlling grain growth in the process of HIP.
