For the first time lithium aluminum titanium phosphate Li1.3 Al0.3Ti1.7 (PO4)3 thick films with NASICON structure have beenobtained by “tape casting” method . A sol-gel method was used to synthesize nanopowder Li1.3 Al0.3Ti1.7(PO4)3. Film-forming solution was obtained based o n previously synthesized nanoparticles and mixed with organic reagents. Films were deposited on the substrate of ?-Al2 O3 and were exposed to isostatic lamination. Sintering thick films were carried out at temperature of 1000°C. Different regimes of heat treatment were studied to determine the optimal conditions of heat treatment . Investigation of structural and morphological characteristics has shown that the maximum dense film is achieved at low heating rate (20°C/h) and by the action of isostatic lamination . Reducing of porosity positively affects electrical properties. Films after isostatic lamination are characterized by high values of Li-ion conductivity. Thus, the laminated film after low rate heating, which has the lowest porosity of 17%, shows the highest values Li-ion conductivity – 5.6?10–6 S/сm.
