氮化铝陶瓷的研制及应用

Development of Aluminum Nitride Ceramics

氮化铝 (AlN)因具有高热导率、低介电常数、与硅相匹配的热膨胀系数及其他优良的物理特性 ,在新材料领域越来越引起人们的关注。此文主要介绍并分析了AlN粉体合成、烧结、性能结构。

The excellent thermal conduction,coupled with other characteristics such as low dielectric constant and the expansion coefficient matched with silicon,makes aluminum nitride a promising materials,especially for electronic substrates.The developments of aluminum nitride ceramics are discussed,including powder preparation,sintering technology,microstructure investigation,as well as their properties and application.
