Phase Transformation Of Sol-Gel Derived Zr02-2Re203 (Re=Sm, Gd And Dy) Spun Fibres By Ageing In Humid Atmosphere

Zirconia fibres doped with 2 equivalent mol% of RE203 (RE=Sm, Gd and Dy) were prepared by spinning of acetate derived sols followed by calcination of the gel fibres thus obtained at 900-1300 deg C for 1h. The oxide fibres were characterized by X-ray diffraction (XRD) analysis. The fibres containing only tetragonal (t) phase were aged under controlled humidity at 150-300 deg C for 8h and in addition at 200 deg C for 2 and 5 hours.
