High-dielectric-constant capacitor material and preparation method thereof
The invention is applicable to the technical field of capacitor materials, and provides a high-dielectric-constant capacitor material and a preparation method thereof. The high-dielectric-constant capacitor material comprises a MgTiO3 material doped with Co, Ni and Zn elements, and Ba6-3xNd8+2xTi18O54 powder doped with Sr, Ca and rare earth elements. According to the invention, MgTiO3 and Ba6-3xNd8+2xTi18O54 are compounded, so that the dielectric constant of the capacitor material can be improved on the premise of ensuring that the capacitor material has a high quality factor. Besides, the Co,Ni and Zn elements are doped in the MgTiO3 material, and Sr, Ca and rare earth elements are doped in the Ba63xNd8+2xTi18O54 powder, so that the dielectric constant of the capacitor material can be further improved.
本发明适用于电容器材料技术领域，提供了一种高介电常数电容器材料及其制备方法，该高介电常数电容器材料包括：掺杂有Co、Ni和Zn元素的MgTiO3材料，以及掺杂有Sr、Ca和稀土元素的Ba6‑3xNd8+2xTi18O54粉体。本发明通过将MgTiO3与Ba6‑3xNd8+2xTi18O54进行复配，可以在保证电容器材料具有高品质因数的前提下，提高电容器材料的介电常数。另外，本发明通过在MgTiO3材料中掺杂Co、Ni和Zn元素，以及在Ba6‑3xNd8+2xTi18O54粉体中掺杂Sr、Ca和稀土元素，可以进一步提高电容器材料的介电常数。
