Microwave dielectric ceramic material as well as preparation method and application thereof
The invention belongs to the technical field of capacitors, and particularly relates to a microwave dielectric ceramic material and a preparation method and application thereof. According to the microwave dielectric ceramic material provided by the invention, Ba (1-x) (M1M2) xNd (2.3-y) ByTi (4.5-z) (S1S2) z is used as a base material; the powder A is used as a glass sintering aid, and the sintering temperature is reduced to 1060-1120 DEG C to realize sintering densification; meanwhile, the performance of the microwave dielectric ceramic material is optimized under the combined action of the powder B, so that the microwave dielectric ceramic material has relatively low dielectric loss and ultrahigh temperature stability. The dielectric loss of the MLCC prepared from the microwave dielectric ceramic material is lower than 2.8 * 10 <-4 >, and the capacity temperature coefficient can be controlled to be (0 +/-15) ppm/DEG C within the range of-55 DEG C to 125 DEG C.
本发明属于电容器技术领域，具体涉及一种微波介质陶瓷材料及其制备方法和应用。本发明提供的微波介质陶瓷材料，以Ba1‑x(M1M2)xNd2.3‑yByTi4.5‑z(S1S2)z作为基体材料；以粉末A作为玻璃助烧剂，降低烧结温度在1060～1120℃实现烧结致密化；同时在粉末B的共同作用下优化微波介质陶瓷材料的性能，使微波介质陶瓷材料具有较低的介电损耗、超高的温度稳定性。利用微波介质陶瓷材料制备得到的MLCC的介电损耗低于2.8×10‑4，在‑55℃～125℃范围内容量温度系数可控制在(0±15)ppm/℃。
