摘要
研究了用叶蜡石、碳酸钙与适量的氧化铝 ,在加入添加剂的条件下 ,用原位反应烧结法制备出低温烧结 ( 12 0 0℃ )的新型钙长石质陶瓷基片材料。在满足使用强度条件下 ,与目前常用的氧化铝质陶瓷基片相比 ,叶蜡石制备出的低温烧结钙长石质陶瓷基片的介电常数小 ,电绝缘性能好 ;体积密度轻 ,对减轻电器设备的质量有利 ;特别是烧成温度低 ,对于采用高导电率导体 ,像铜、银、金等引线的要求十分有利 ,且原料价格低 ,有很好的经济效益。并讨论了CaCO3 原料适当的引入粒度和Al2 O3 的加入量的影响。
In this paper,it has been emphatically described how to prepare the low sintering temperature anorthite substrate(1200℃)with pyrophyllite,calcium carbonate and suitable aluminum by adding to additive.Under contented the used intensity,the anorthite ceramic substrate which prepared with pyrophyllite at low-sintering temperature has small dielectric constant,good dielectric property which compared with common aluminum substrate,the anorthite ceramic substrate has light bulk density,which is advantage to reduce the weight of the electric equipment,especially,it has low-sintering temperautre,which is very benefit to take high electric conductivity materials,such as copper,silver,gold,moreover,the raw materials price is low,which has good economic benefit.In the paper,is has been too probed into the effects of particle size of CaCO 3 and content of Al 2O 3 on the substrate.
