【摘要】：为了研究锆钛酸铅压电陶瓷烧成用氧化铝陶瓷承烧板的损坏机制,对在锆钛酸铅压电陶瓷烧成中使用80次后的氧化铝陶瓷承烧板的显微结构和化学组成的变化进行了分析,探讨了氧化铝陶瓷承烧板被侵蚀的过程及发生翘曲、表面粉化、剥落的原因。研究认为:氧化铝陶瓷承烧板被锆钛酸铅组分侵蚀,是从其颗粒表面逐渐向颗粒内部深入的;碳化硅推板加速了氧化铝陶瓷承烧板的损坏。锆钛酸铅组分侵入以及承烧板底面生成玻璃相,两者共同作用,导致了氧化铝陶瓷承烧板中心凸起翘曲及表面层状粉化剥落。
[Abstract]:In order to study the damage mechanism of alumina ceramic sintered plate for lead zirconate titanate ceramic sintering, the microstructure and chemical composition of alumina ceramic bearing plate after 80 times firing were analyzed. The process of erosion of alumina ceramic board and the causes of warpage, surface pulverization and spalling are discussed. The results show that the alumina ceramic plate is corroded by lead zirconate titanate from the surface of the particle to the interior of the particle and the silicon carbide plate accelerates the damage of the ceramic board. The intrusion of lead zirconate titanate and the formation of glass phase on the bottom of the sintered plate resulted in the central warping of alumina ceramic board and the surface layer flaking.
