Method for improving sintering relative density of lithium lanthanum zirconium oxide ceramic wafer
The invention provides a method for improving the sintering relative density of a lithium lanthanum zirconium oxide (LLZO) ceramic wafer, and the relative density of the sintered lithium lanthanum zirconium oxide ceramic wafer is improved by adding powder with the same components at the upper side and the lower side of the lithium lanthanum zirconium oxide ceramic wafer and introducing gas during sintering. According to the novel method for sintering the LLZO ceramic, a novel method for sintering the LLZO ceramic chip is found, the relative density of the sintered LLZO ceramic chip is greatly improved, and the design has the advantages that the relative density of the sintered and molded LLZO ceramic chip is 95% or above, defects such as air holes and microcracks in the finished product LLZO ceramic chip are few, the grain size of crystal grains is uniform, the crystal grains are tightly combined, and the service life of the LLZO ceramic chip is prolonged. The method is simple in steps, suitable for large-scale production and good in application prospect, and has excellent ionic conductivity and better mechanical property.
本发明提供一种提高锂镧锆氧（LLZO）陶瓷片烧结相对密度的方法，通过在烧结时于锂镧锆氧陶瓷片上下两侧添加相同成分粉末以及通入气体来提高烧结后锂镧锆氧陶瓷片的相对密度，所述新型烧结LLZO陶瓷的方法为寻找一种新的烧结LLZO陶瓷片的方法，使烧结LLZO陶瓷片的相对密度大幅提高，该设计的优点在于烧结成型后的LLZO陶瓷片相对密度在95%以上，成品LLZO陶瓷片内部气孔以及微裂纹等缺陷较少，晶粒粒径均匀且结合紧密，具有优良的离子电导性能以及较好的力学性能，该方法步骤简单，适用于大批量生产，具有很好的应用前景。
