Effects of Yttrium Doping Ξ±-Alumina. Part 1. Microstructure and Microchemistry. -In hot-pressed Ξ±-Al 2 O 3 doped with 1000 ppm Y, yttrium exists at grain boundaries as a segregant ion and in second phase Y 3 Al 5 O 12 (YAG) particles. The doped ceramics show a bimodal grain-size distribution that i
