采用熔体急冷法制备了Li 1，3 Ti 0，7Al 0，3（PO 4）（3）（LATP）粉体，并采用场辅助烧结技术（FAST）在不同温度下进行烧结。使用这种技术，样品可以根据烧结条件烧结到93至99%的相对密度。离子和热导率进行了测量，并根据XRD和SEM分析的结果进行了讨论。使用相对较大的颗粒和1000 ℃的烧结温度，在50 MPa的单轴压力下，在室温下获得2 W/mK的热导率值和4 × 10（-4）S cm（-1）的离子电导率。
Li1,3Ti0,7Al0,3(PO4)(3) (LATP) powder was obtained by a conventional melt-quenching method and consolidated by field-assisted sintering technology (FAST) at different temperatures. Using this technique, the samples could be sintered to relative densities in the range of 93 to 99 % depending on the sintering conditions. Ionic and thermal conductivity were measured and the results are discussed under consideration of XRD and SEManalyses. Thermal conductivity values of 2W/mK and ionic conductivities of 4 x 10(-4) S cm(-1) at room temperature were obtained using relatively large particles and a sintering temperature of 1000 degrees C at an applied uniaxial pressure of 50 MPa.
