Suppressing the Powdering of Zirconia Fibers after High-Temperature Application by Large Additions of Yttria

Abstract:

Zirconia fibers with different Y₂O₃ additions were prepared by sol-gel method. After the fiber was thermally treated at 1650°C for 6h, the microstructure and crystalline phase were investigated by scanning electron microscope and X-ray diffraction. It was found that the fibers with 5mol% of Y₂O₃ seriously powdered due to volume expansion caused by the phase transformation form tetragonal phase to monoclinic phase. The powdering of zirconia fibers after high–temperature application could be depressed when the amount of Y₂O₃ was more than 10mol%.
