摘要

选用MgO-CuO-TiO₂-Eu₂O₃添加剂作为氧化铝陶瓷的烧结助剂，在空气气氛下经过常压烧结制备Al₂O₃陶瓷。采用XRD，SEM及EDS等方法研究Eu₂O₃掺杂量以及烧结温度对Al₂O₃基微波陶瓷样品物相组成，微观结构和介电性能的影响。结果表明：添加Eu₂O₃的Al₂O₃陶瓷中，均存在Al₂Eu₂O₉次晶相，且随着Eu₂O₃含量的增加，Al₂Eu₂O₉相增加；随着Eu₂O₃添加量的增加，Al₂O₃陶瓷试样致密度先增加后降低；随着烧结温度的增加，Al₂O₃陶瓷的介电常数和品质因数Q·f值先增加后降低。烧结温度为1450℃，Eu₂O₃添加量为0.25%（质量分数）时，烧结体的相对密度达到最大值98.21%，且Al₂O₃陶瓷的介电性能较好：介电常数为10.05，品质因数Q·f为37984GHz。

Abstract：

A kind of alumina ceramic was prepared by atmospheric pressure sintering under air atmosphere using MgO-CuO-TiO₂-Eu₂O₃ as sintering additive. The effect of Eu₂O₃ doping amount and sintering temperature on the phase composition, microstructure as well as dielectric properties of Al₂O₃-based microwave ceramic samples was studied by XRD, SEM and EDS. The results show that the Al₂Eu₂O₉ secondary crystalline phase is present in all Al₂O₃ ceramics with Eu₂O₃ addition, and the Al₂Eu₂O₉ phase is enhanced with the increase of Eu₂O₃ content. With higher Eu₂O₃ content, the density of Al₂O₃ ceramics increases first and then decreases. As sintering temperature increases, the dielectric constant and quality factor Q·f of Al₂O₃ ceramics increase first and then decrease. When the sintering temperature rises up to 1450℃ and the content of Eu₂O₃ is 0.25%(mass fraction), the relative density of the sintered body reaches to the maximum of 98.21%, and the dielectric properties of the Al₂O₃ ceramics are superior with the dielectric constant 10.05 and the quality factor Q·f 37984GHz.

Key words： alumina ceramic Eu₂O₃ doping density dielectric property
