Paper Title:
Preparation and Characterization of Zirconia-Based Multi-Phase Nanocomposite
  Abstract

ZrO2 (3Y)-CaO-SiO2-TiO2 powders with excellent chemical homogeneity were synthesized by heating the alcohol-aqueous salt solutions. The powders have good dispersion, with particle size of 11~15nm and no hard agglomeration. The nanocomposite powders were hot-pressed in vacuum. The obtained zirconia-based multi-phase nanocomposites were characterized by using XRD and SEM, as well as relative density testing. The results demonstrated that, even though the sintering temperature was as low as 1250°C, a high relative density of 97.5% was achieved. The superplastic compressive tests of the as-sintered specimens demonstrate that this material behaves good deformability at 1350~1500°C, at which the maximum extrusion pressure is lower than 35MPa.
