%X The sintering behavior of YRE-ZrO2 powder observed in dilatometric experiments is shown in this work. The powder analyzed was composed by ZrO2 and 6 wt% of YRE oxides mixture, which were added to stabilize the zirconia tetragonal phase. The powder mixtures obtained from controlled zirconium chloride and yttrium and rare earth chloride coprecipitation were calcined at 400degreesC. Isostatic pressing at 400MPa compacted the powder and the sintering was realized at constant heating rate of 10degreesC/min up to 1600degreesC. At this temperature it was realized an isothermal treatment during I hour. The results showed three different stages of sintering during heating, being the two initials stages exhibiting a shrinkage behavior, similar to the majority of the ceramic systems. In the third stage, above 1240degreesC, it was observed a small dilation, which suggests the tetragonal to monoclinic phase transformation in zirconia ceramic. Samples also were conventionally sintered at temperature range between 1200 to 1600degreesC. The X-ray diffraction results and SEM observations were carried out to characterize both the powder mixture and the microstructures of the ceramic bodies. These results were correlated and discussed.
