Abstract

Polycrystalline oxide fibers have not yet been exploited to their full potential, perhaps because of difficulties with processability. In the successful new route for the production of continuous yttria-stabilized zirconia fibers detailed here, ZrO2 particles sols are used as oxide-forming components. The fine-grained compact ceramic fibers of tetragonal zirconia polycrystals obtained 2 mol-% Y2O3 are shown in the figure.
