X8R type multilayer ceramic capacitor ceramic material and preparation method thereof
The invention discloses an X8R type multilayer ceramic capacitor ceramic material and a preparation method thereof, and belongs to the field of ceramic materials of electronic components. The X8R type multilayer ceramic capacitor ceramic material comprises a main component of 0.9 BaTiO3-0.1 Na0. 5Bi0. 5TiO3 and an additive comprising Bi2O3, MgO, an oxide of R1 and an oxide of R2, wherein R1 and R2 are selected from different rare earth elements. By limiting the components and contents of the additives, the obtained X8R type ceramic capacitor ceramic material has a wide temperature stability range and low dielectric loss. The preparation process of the X8R type ceramic capacitor ceramic material is simple, and medium-temperature sintering can be carried out by utilizing a traditional solid phase method, so that the production cost is reduced, and the industrial development is accelerated.
一种X8R型多层陶瓷电容器瓷料及其制备方法，属于电子元器件的陶瓷材料领域。X8R型多层陶瓷电容器瓷料包括0.9BaTiO3‑0.1Na0.5Bi0.5TiO3的主成分和包括Bi2O3、MgO、R1的氧化物和R2的氧化物的添加剂，R1和R2选自不同的稀土元素。通过限制各添加剂的成分和含量，使得获得的X8R型陶瓷电容器瓷料具有宽的温度稳定性范围、低的介电损耗。上述X8R型陶瓷电容器瓷料的制备工艺简单，可利用传统固相法进行中温烧结，以降低生产成本和加快产业化发展。
