Polycrystalline Y2O3 doped tetragonal ZrO2 fibers, with and without Al2O3, were fabricated by the sol-gel method. The fibers were produced by spinning a ZrO2 sol containing Y2O3 and Al2O3 precursors, and a polymer to control viscosities. The fibers consist of fine-grained tetragonal ZrO2 and elongated Al2O3 and are 99% dense. The effect of the addition of Al2O3 on the microstructure of the ZrO2 fibers was investigated with respect to heat treatment up to 1500°C.
