## The influence of yttrium on the microstructure and toughness of a-alumina is studied as a function of oxygen partial pressure and chemical state of the doping element. For doping amounts higher than 0.03 mol% of Y,O,, Y,AI,O,, garnet precipitates and the alumina grain size is then limited by such
