AB - Hot-press sintering of AlN ceramics were carried out with Y₂O₃as sintering additive at a sintering temperature 1,750~1,850℃. The effect of Y₂O₃addition and sintering time on sintering behavior and thermal conductivity of AlN
ceramics was investigated. Y₂O₃added AlN showed noticeably higher densification rate than pure AlN. The thermal conductivity of AlN specimens was promoted by the addition of Y₂O₃in spite of the formation of YAG secondary phase in AlN grain boundaries and grain boundary triple junction because Y₂O₃addition could reduced the oxygen contents in AlN lattice which is primary factor of thermal conductivity. Typically, the thermal conductivity of 5 wt% Y₂O₃added specimen was dramatically improved by the increase of sintering time because the elimination of YAG secondary phases
from the grain boundary due to the evaporation, as well as the grain-growth of AlN grains.
