Ultralow-loss low-temperature sintering microwave ceramic material and preparation method thereof
The invention belongs to the technical field of electronic ceramic materials and manufacturing of the electronic ceramic materials, and discloses an ultralow-loss low-temperature sintering microwave ceramic material and a preparation method of the ultralow-loss low-temperature sintering microwave ceramic material, and the ultralow-loss low-temperature sintering microwave ceramic material is obtained by carrying out three-phase compounding on a proper amount of Li3Mg2NbO6, Li2WO4 and (Li0. 5Y0. 5) MoO4 according to a certain proportion. The Li3Mg2NbO6 material has the advantages that the dielectric loss is very low, meanwhile, a proper amount of Li2WO4 is compounded and added, so that the microstructure of a material system is improved, the densification degree is improved, and the sintering temperature of the material system is reduced to 925-950 DEG C while the very low dielectric loss is maintained. And by compounding a proper amount of (Li0. 5Y0. 5) MoO4, on one hand, the sintering temperature of a material system can be further reduced to 890-900 DEG C, so that the material can be better compatible with an LTCC (Low Temperature Co-Fired Ceramic) process, and meanwhile, the temperature coefficient of resonance frequency of the material can be regulated and controlled.
本发明属于电子陶瓷材料及其制造技术领域，公开了一种超低损耗低温烧结微波陶瓷材料及其制备方法，本发明提供的LTCC材料，采用适量的Li3Mg2NbO6、Li2WO4和(Li0.5Y0.5)MoO4按一定比例进行三相复合得到。Li3Mg2NbO6材料的优点是具有很低的介电损耗，同时复合加入适量的Li2WO4则有助于改善材料体系的微观形貌，提升致密化程度，在维持很低介电损耗的同时，将材料体系的烧结温度降低至925～950℃。而适量(Li0.5Y0.5)MoO4的复合一方面可以进一步将材料体系烧结温度进一步降低至890～900℃，从而能更好的与LTCC工艺兼容，同时还能调控材料的谐振频率温度系数。
