摘要: 介绍一种由高热导率AlN陶瓷和金属W共烧制备低温AlN陶瓷基片的排胶技术.研究了排胶过程中残余碳对AlN陶瓷基片相组成、烧结特性和微观结构的影响.结果表明:两步排胶法可以较好地解决W氧化及AlN陶瓷颗粒表面吸附残余碳的问题.

关键词: AlN陶瓷, 低温共烧, 排胶, 残余碳

Abstract: A technique of burn-out for low temperature cofired AlN multilayer substrates was introduced,which consist of high thermal conductivity AlN ceramics and metal W. The effect of the evolutionof carbon during burn-out on AlN sintering characteristics and microstructure was studied. Theresults showed that two-step burn-out process may solve the contradiction between W oxidationand residual carbon.

Key words: aluminium nitride, low temperature cofire, binder burn-out, residual carbon
