Title: Three-dimensional analysis by serial sectioning of cubic zirconia sinters

Abstract

Three-dimensional electron backscatter diffraction technique was used for the characterization of grain boundary geometry and pore morphology in cubic zirconia. A set of three samples composed of cubic yttria stabilized zirconia, sintered under different conditions was investigated. Analysis of grain boundaries and pore structure was carried out in a dual-beam scanning electron microscope. For each sample, a volume of 15·10{sup 3} μm{sup 3} was investigated. The results of three-dimensional microstructure analysis were compared to the results derived from regular, two-dimensional maps of the area of 2500 µm{sup 2}. Based on two-dimensional and three-dimensional data the average grain diameter, number of grains, average number of neighbors and porosity were calculated. The average grain diameter varied in the range from 2.39 µm to 2.91 µm and from 3.00 µm to 3.79 µm, while the level of porosity varied in the range from 1.22% to 1.77% and from 1.30% to 5.61% for two-dimensional and three-dimensional data, respectively. The analysis of grain boundary networks revealed a strong dependence between grain boundary density and sample preparation parameters. The parameters of the sintering process affected also the size and distribution of pores. The comparison of the results of 2D and 3D materials characterization revealed significant differences in the values of calculatedmore » microstructure parameters.« less
