SPHERICAL, VOID-FREE PARTICLE FORMATION IN SPRAY-DRIED FERRITES

Ferrite beads prepared via spray drying of a slurry of mixed oxides have characteristic voids or dimples present in the dried particles. This invention relates to the preparation of a slurry of ferrite forming metal oxides in a liquid wherein the slurry has a viscosity at about 23.degree.C of betwee...
