| 摘 要： | 给出了氧化铝陶瓷、微波陶瓷及PTC热敏陶瓷等几种电子材料的一些研究成果。发现95%~97%Al2O3陶瓷的机械强度不仅和晶体大小，而且和形貌及分布有关。制备的(Zr，Sn)TiO4微波陶瓷的?r为35~41，?f为(-14~+20) ×10-6℃-1和Q0≥5 000 (10 GHz)。采用化学共沉淀法制备了超细 (Ba，Sr，Pb) TiO3粉并获得了高性能PTC热敏陶瓷。对研究成果产业化进展提出若干思考问题并进行了探讨。

| Abstract: | Presented are the research results of some electronic ceramic materials, including alumina ceramics and PTC thermal sensitive ceramics. It is found that of 95%~97% Al2O3 the mechanical strength depends on its crystalline size, morphology and distribution. Of the acquired (Zr, Sn)TiO4 ceramics for microwave application, er is 35~41, tf (－14~＋20)×106C－1, and Q0≥5 000 (10 GHz).Ultra-fine (Ba, Sr, Pb) TiO3 powder is prepared by co-precipitation and high performance PTC thermal-sensitive ceramics is obtained.
