NaSICON型锂导体Li1.3Al0.3Ti1.7（PO 4）（3）（LATP）使用溶液化学合成，具有受控的晶粒尺寸和组成。在850 ℃热处理后，获得具有高纯度的亚微米晶化粉末。它们通过850-1000摄氏度的火花等离子烧结转化为陶瓷。通过改变工艺参数，获得了电导率达1.6 × 10 ~（-4）S/cm、密度为理论密度97%的球团矿。采用XRD、FEG-SEM、交流阻抗和维氏硬度等测试手段对产物进行了表征。讨论了烧结工艺参数对球团成分、显微结构和电导率的影响，并分析了颗粒界面的力学行为。(C)2012爱思唯尔有限公司保留所有权利。
NaSICON-type lithium conductor Li1.3Al0.3Ti1.7(PO4)(3) (LATP) is synthesized with controlled grain size and composition using solution chemistry. After thermal treatment at 850 degrees C, sub-micronic crystallized powders with high purity are obtained. They are converted into ceramic through Spark Plasma Sintering at 850-1000 degrees C. By varying the processing parameters, pellet with conductivities up to 1.6 x 10(-4) S/cm with density of 97% of the theoretical density have been obtained. XRD, FEG-SEM, ac-impedance and Vickers indentation were used to characterize the products. The influence of sintering parameters on pellet composition, microstructure and conductivity is discussed in addition to the analysis of the mechanical behavior of the grains interfaces.
