Materials La0.9Sr0.1Ga0.8Mg0.2O3 and La0.8Sr0.2Ga0.83Mg0.17-xCoxO3 with x=0, 0.05, 0.085, 0.10 and 0.15 are synthesized by laser rapid sintering (LRS). It is found that the total conductivities of La0.8Sr0.2Ga0.83Mg0.17-xCoxO3 by LRS are obviously improved by Co doping, showing a general increase with the content Co except that for x=0.15. The conductivities of the La0.9Sr0.1Ga0.8Mg0.2O3 and La0.8Sr0.2Ga0.83Mg0.085Co0.085O3 samples synthesized by LRS are superior to those of both samples for the same compositions by solid state reaction (SSR) at any temperatures. The conductivities of La0.9Sr0.1Ga0.8Mg0.2O3 and La0.8Sr0.2Ga0.83Mg0.085Co0.085O3 samples synthesized by LRS are about twice and thrice as much as those of the samples for the same compositions synthesized by SSR, respectively. The improved conductivities of La0.9Sr0.1Ga0.8Mg0.2O3 and La0.8Sr0.2Ga0.83Mg0.085Co0.085O3 prepared by laser rapid sintering with respect to that by solid state reactions for the same composition is attributed to the unique microstructures of the samples generated during laser rapid sintering.
