本文采用Y－Si－Al－O－N系氧氮玻璃对Si3N4陶瓷进行1450、1600℃保温30min的润湿实验和连接实验．结果表明，氧氮玻璃对Si3N4的润湿性较好，1450℃时两者的热膨胀系数差异明显，而1600℃时热膨胀系数差异减小，接头附近存在扩散区．氧氮玻璃可以连接Si3N4陶瓷．
-Si-Al-O-N glass was used to bond and wet dense Si3N4 ceramic at 1450℃ and 16000℃ for30 min, respectively. The result showed that the oxynitride glass can wet well to Si3N4 ceramic.At 14500℃, there was obvious d
