ALUMINUM NITRIDE SINTERED BODY AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide an aluminum nitride sintered body having improved mechanical strength without impairing heat dissipation property.SOLUTION: The aluminum nitride sintered body contains 100 parts by weight of AlN, at least one kind of nitride of an element selected from a group of Zr and Ti in an amount of 3 to 20 parts by weight in terms of oxide as an additive, and 10 parts by weight of YOas a sintering aid. The sintered body has an oxygen content of 1.8 wt.% or less, and a thermal conductivity of 130 W/m K or more.SELECTED DRAWING: Figure 1
【課題】放熱特性を損なうことなく機械的強度を高めた窒化アルミニウム焼結体を提供する。【解決手段】窒化アルミニウム焼結体は、１００重量部のＡｌＮと、添加剤として酸化物換算で３〜２０重量部のＺｒ、Ｔｉの群から選択される窒化物の少なくとも一種と、焼結助剤として１〜１０重量部のＹ２Ｏ３とを含有する窒化アルミニウム焼結体であって、焼結体中の酸素含有量が１．８重量％以下であり、熱伝導率が１３０Ｗ／ｍ・Ｋ以上である。【選択図】図１
