ABSTRACT:
Homogeneous, nonporous ceramic fibers containing at least one magnetically-unaligned, microcrystaline transition metal oxide spinel phase. The ceramic fibers may be used in polymeric, ceramic and metallic composites. Said ceramic spinel is produced by dispersing soluble inorganic and transition metal compounds in an aqueous mixture, concentrating to produce a viscous concentrate, shaping into the desired article, gelling the shaped article, and heating to produce the transition metal spinel article. Beads, bubbles, flakes, microspheres, films and granules may be made as well as fibers.
