Abstract
In this research, a sol-gel auto combustion route has been proposed to synthesize LaAlO3 nanopowders, using lanthanum nitrate, aluminum hexahydrate, and different fuels such as citric acid, oxalic acid, and tartaric acid. The formation temperature of LaAlO3 and its crystallite size in the presence of different fuels were compared together. The results showed that the lowest formation temperature as well as the smallest crystallite size in the presence of citric acid was 750 degrees C and 28.7nm.
