Abstract
Ceramic metal oxide fibers are made by intercalating graphitic graphite fibers with a mixture of metal chlorides and then heating the intercalated fibers to oxidize or burn off the carbon leaving a metal oxide fiber having generally the shape and structure of the graphite fiber precursors to make composite fibers, such as binary fibers of aluminum oxide-zirconium oxide and aluminum oxide-ferric oxide.
