两种不同AIN粉末的烧结和热传导特性比较

Compare of Sintering and Thermal Conductivity between Two Kinds of AlN Powders

本文对Ａｌ＿２Ｏ＿３碳还原氮化法和Ａｌ直接氮化法所制作的两种ＡｌＮ粉体的特性进行了分析和比较，然后研究了这两种粉体在添加０～１５ｗｔ．％的Ｙ＿２Ｏ＿３烧结助剂的条件下，经２０７３Ｋ烧结后的密度变化以及在室温下的热传导特性。

In this paper,we have compared thecharacters of two kinds of AlN powders which werepropared respectively by the carbonthermal reduction method and the direct nitriding n1ethod.Withadditives of 0～15 wt%Y_2O_3,in the two kinds ofAlN,their densities after sintering at 2073 K andtheir thermal conductivities at rooni temperaturehave been investigated.
