La0.67LixTi1-xAlxO3 ceramics (x = 0.05, 0.10, 0.15, 0.20, 0.25, 0.30) were synthesized with the use of Al2O3 and an aqueous solution Al(NO3)3 as aluminium source. In both cases, preserve a high dielectric constant ε ~ 105. It was found that single-phase perovskite structure is formed at temperatures above 1200 C. shown allows simplifying synthesis: reduction in sintering temperature by 20 C, Li...
