摘要:	The pure perovskite La0.3Sr0.7Ti0.9Nb0.1O3 (LSTN) with high densification and conductivity was achieved by 1500 degrees C conventional sintering (CS) in activated carbon reduction atmosphere. The low conductivity of porous LSTN was obtained for low sintering temperature 1300 degrees C in same process. Porous and well-crystallized LSTN could be obtained by microwave reduction sintering (MS). The activated carbon post-treatment with long dwell time improved the conductivities of microwave sintered LSTN samples. The conductivity of microwave sintered LSTN increased fast in short post-reduction time and was higher than conventional sintered LSTN for same sintering temperature. The microwave sintering essentially modified the LSTN electrical properties.
