Al2-xNdxMo3O12 microwave dielectric ceramic material with high quality factor and preparation method of Al2-xNdxMo3O12 microwave dielectric ceramic material
The invention discloses a high-quality-factor Al < 2-x > Nd < x > Mo3O12 microwave dielectric ceramic material and a preparation method thereof.The preparation method comprises the steps that original powder of Al2O3, original powder of Nd < 2 > O < 3 > and original powder of MoO < 3 > are blended according to the chemical general formula Al < 2-x > Nd < x > Mo3O12, and mixed powder is obtained; carrying out planetary ball milling on the mixed powder, drying, sieving and pre-sintering to obtain a pre-sintered material; carrying out planetary ball milling on the pre-sintered material again, drying and granulating to form a ceramic raw material; and carrying out compression molding on the ceramic raw material, and carrying out glue discharging to form the Al < 2-x > Nd < x > Mo3O12 microwave dielectric ceramic material. According to the invention, the formation rule of a solid solution is taken as guidance, a small amount of Nd < 3 + > ions are used for replacing Al2O3, a low-temperature solid solution phase is formed by occupying crystal lattice sites, the sintering temperature and the heat preservation time of the ceramic material are reduced, and the ceramic material has a relatively low dielectric constant and a very excellent Q * f value.
本发明公开了一种高品质因数的Al2‑xNdxMo3O12微波介质陶瓷材料及其制备方法，所述制备方法包括：将Al2O3、Nd2O3和MoO3的原始粉料按照化学通式Al2‑xNdxMo3O12进行配料，获得混合粉料；对所述混合粉料进行行星球磨，并进行烘干、过筛和预烧，获得预烧料；将所述预烧料再次进行行星球磨，并进行烘干和造粒，形成陶瓷生料；将所述陶瓷生料压制成型并进行排胶，形成Al2‑xNdxMo3O12微波介质陶瓷材料。本发明以固溶体的形成规则为指导，以Nd3+离子少量取代Al2O3，通过占据晶格格位形成低温固溶相，降低了陶瓷材料的烧结温度和保温时间，并具有较低的介电常数和十分优异的Q×f值。
