• Al-doped ZnO sintered bodies, which were doped with 0–2 mol % Al2O3, were prepared from a powder mixture. Al could dissolve in ZnO grains uniformly and a fraction of Al tended to segregate along ZnO grain boundaries when the Al concentration was low. The decrease in the [$c/a$] lattice ratio suggested that the solubility of Al in ZnO increased with increasing concentration of Al2O3. The solubility of Al reached the limit when Al2O3 was doped at more than 1 mol %. ZnAl2O4 particles appeared before the solubility of Al reached the limit, indicating that the dissolution of Al and the formation of ZnAl2O4 phases occurred simultaneously in the Al2O3–ZnO sintering process.
