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%.

High-temperature brazing molybdenum using palladium and titanium foils have been investigated in the experiment. Successful brazed joints are achieved from using the palladium filler foil. Brazed joints are fully dense and free of any intermetallic phase. Three point bending strengths of 246 and 233 MPa are obtained from joints using 100 m thick palladium filler foil brazed at 1580 and 1610 oC for 600 s, respectively. The application of palladium filler foil shows potential in brazing molybdenum for high-temperature application.
