摘要：

The 8-mol percentage Y2O3-stabilized Porous Zirconia was prepared using sol-gel method. Zirconium oxalate gel was prepared by the addition of appropriate amount of oxalic acid solution into the I M aqueous solution of zirconium-oxy chloride. A cubic phase zirconia powder was obtained by calcination and milling of the zirconium oxalate gel. Crystallization temperature was found about 450 degrees C from the Differential thermal analysis. The phase analysis by X-ray diffraction shows the presence of cubic phase. Pellets sintered at 1,350 degrees C were highly porous, and the electrical conductivity was found with lower value due to the porosity, and the hardness was about 8.0 GPa.
