摘要
本文用热压法烧结制备出ＡｌＮ—ＢＮ复合陶瓷，讨论了组成及烧结条件对ＡｌＮ—ＢＮ复合陶瓷性能及显微结构的影响。通过优化组成，使ＡｌＮ—ＢＮ复合陶瓷垂直于加压方向的导热率最大达１０３Ｗ／ｍ·Ｋ。ＡｌＮ—ＢＮ复合陶瓷的导热率和显微结构各向异性较显著。
AlN BN composite ceramic was manufactured by hot pressed sintering method.In the paper,the effects of the composition and sintering conditions of AlN BN composite ceramic on its properties and microstructure are discussed.By optimizing the composition, the heat conductivity of the ceramic perpendicular to the pressing direction is raised up to 103 W/m·K.The anisotropy of the heat conductivity and the microstructure of the AlN BN composite ceramic is quite appareat.
