Aluminum nitride sintered body |
| abstract |
A high-purity aluminum nitride sintered body is provided by efficiently removing oxides contained in a raw material powder in producing an aluminum nitride sintered body and preventing composite oxide produced by reaction of oxides contained in the raw material powder with a sintering aid from remaining in the aluminum nitride sintered body. The above sintered body is achieved by an aluminum nitride sintered body having a concentration of residual oxygen excluding attached oxygen of 350 ppm or less. |
