    Abstract: Provided is an alumina-based sintered body and a manufacturing method thereof, wherein the tissue of the sintered body is uniform and processability is improved, thereby the original color of the sintered body is maintained. The alumina-based sintered body is formed in a crystal lattice and a particle phase and includes 0.08-0.30 wt% of titanium or titanium compounds, inclusively, in terms of titanium oxide. Since titanium or titanium compounds exist in a crystal lattice, grain growth is promoted. Therefore, the tissue of the sintered body becomes uniform and processability is improved. Moreover, the generation of aluminum titanate and oxygen deficiency in titanium oxide is hard to occur.
