Aluminum nitride sintered body and method for producing same
An aluminum nitride sintered body with improved mechanical strength without compromised thermal dissipating properties. The aluminum nitride sintered body contains 100 parts by weight of AlN, 3 to 20 parts by weight on an oxide basis of at least one type of nitride selected from the group consisting of Zr and Ti as an additive, and 1 to 10 parts by weight of Y2O3 as a sintering aid. The oxygen content in the sintered body is 1.8 wt % or less, and the thermal conductivity is 130 W/m·K or higher.
