Abstract

A process for producing ferrite materials, which comprises preparing a ferrite-forming metal oxide slurry in a liquid, spray drying said slurry of said ferrite-forming metal oxides so as to form substantially spherical metal oxide beads, and concreting said substantially spherical metal oxide beads to form ferrite beads while maintaining the spherical shape and particulate nature of the beads.
