采用一种新的玻璃晶化法合成了具有Na超离子导体（NASICON）结构的Li1.4Al0.4Ti1.6（PO 4）3（LATP）。首先，通过在空气中将原料LiPO 3、Li 2CO 3、Al（PO 3）3和TiO 2在1300 °C下加热1小时来制备玻璃样品，然后对玻璃样品进行两步热处理以合成LATP。Li 2 Ti 2（PO 4）3颗粒在460°C下第一次热处理2 h期间在玻璃样品中形成，随后在720°C下第二次热处理20 h期间Li 2 Ti 2（PO 4）3变为LATP。所得LATP细粉具有尖锐的粒度分布，50%积分直径为1.9 μm。通过使用LATP细粉末在1000 ℃下制造的LATP烧结体的离子电导率在25 ℃下为1.34 × 10 - 5S cm-1，这比通过常规方法获得的离子电导率高上级。
Li1.4Al0.4Ti1.6(PO4)3(LATP) with a Na super ionic conductor (NASICON)-structure was successfully synthesized by a novel glass-crystallization method. First, glass specimens were prepared by heating raw materials LiPO3, Li2CO3, Al(PO3)3, and TiO2at 1300 °C for 1 h in air, and then a two-step heat treatment was performed on the glass specimens to synthesize the LATP. Li2Ti2(PO4)3particles formed in the glass specimen during the first heat treatment at 460°C for 2 h, followed by a change of Li2Ti2(PO4)3to LATP during the second heat treatment at 720°C for 20 h. The resultant fine LATP powder had a sharp particle-size distribution with a 50% integrated diameter of 1.9 μm. The ionic conductivity of the LATP-sintered body that was fabricated at 1000 °C by using the LATP fine powder was 1.34 × 10−5S cm−1at 25 °C, which was superior to that obtained by a conventional method.
