Preparation method of temperature-stable light microwave dielectric ceramic
The invention provides a preparation method of temperature-stable light microwave dielectric ceramic, and belongs to the technical field of electronic ceramic. The temperature-stable light microwave dielectric ceramic provided by the invention is of a three-layer structure, the upper layer and the lower layer are of a light porous structure, and the middle layer is of a compact structure. A composition expression formula is yBa4Sm < 7.5 > Nd < 2 > Ti < 18 > O < 54-x > Ba4Sm < 7.5 > Nd < 2 > Ti < 18 > O < 54-y > Ba4Sm < 7.5 > Nd < 2 > Ti < 18 > O < 54 >, in the formula, x is 0.5-0.9 g, and y is (1.1-x)/2 g. The temperature-stable light microwave dielectric ceramic provided by the invention is good in temperature stability, and can maintain a high dielectric constant and a relatively high Qf value at the same time.
本发明提供了一种温度稳定型轻质微波介质陶瓷的制备方法，属于电子陶瓷技术领域。本发明提供的温度稳定型轻质微波介质陶瓷为三层结构，上下两层为轻质多孔结构，中间层为致密结构。组成表达式为yBa4Sm7.5Nd2Ti18O54‑xBa4Sm7.5Nd2Ti18O54‑yBa4Sm7.5Nd2Ti18O54，式中x为0.5‑0.9g，y为(1.1‑x)/2g。本发明提供的温度稳定型轻质微波介质陶瓷温度稳定性好，同时可以保持高的介电常数和较高的Qf值。
