    Characterization of the microstructure of YAG ceramics via stereology-based image analysis

  • Original language description

    The microstructure of transparent YAG ceramics is investigated by stereology-based microscopic image analysis using SEM and FE-SEM micrographs. Interface densities, mean curvature integral densities and the related grain size measures (mean chord lengthand Jeffries size) have been determined with relative errors of 9-12 % for interface densities and mean curvature integral densities and 6-9 % for the corresponding grain size measures. A comparison of the two grain size measures confi rmed an excellentlinear correlation between the Jeffries size and the mean chord length, with a mean-chordlength- to-Jeffries-size ratio of 0.928 +- 0.086. The overall range of average grain sizes is approx. 11-34 mým. It has been found that the sintering time has a signifi cant infl uence on the grain size, especially for YAG ceramics without Yb doping. When the sintering time is increased by a factor 8 (from 2 h to 16 h) the grain size increases by more than 200 % in undoped YAG ceramics, whereas the g
