Paper Title:
Microstructure Evolution in Samples Prepared by Filter Pressing and Sintering of Zirconia Nanopowder
  Abstract

The aim of this work was the investigation of microstructure evolution during sintering of zirconia nanopowder. The powder containing 97 mol. % ZrO2 and 3 mol. %Y2O3, with particle size about 8 nm was prepared by the hydrothermal method. The flocculated and dispersed water suspensions of the powder were filter pressed under 5 MPa, which led to green bodies of relative density about 40%. Samples prepared from the suspensions showed distinct differences in densification behaviour. The observation of the microstructure evolution (i.e. density, fracture surface) in samples heat-treated at different temperatures, and detailed analysis of open porosity evolution were performed.
