| 中文摘要 | the effects of moo(3) concentration on the sintering and electrical properties of ce(0.8)nd(0.2)o(1.9) + 500 ppm sio(2) (ndcsi) and (ce(0.8)nd(0.2)o(1.9))(1 -) (x)(moo(3))(x) + 500 ppm sio(2) (x = 0.01, 0.02, 0.03, 0.04, 0.05, ndcsi + 1moo(3), ndcsi + 2moo(3), ndcsi + 3moo(3), ndcsi + 4moo(3), ndcsi + 5moo(3)) prepared through a modified sol-gel method were systematically investigated. the structures and ionic conductivities were characterized by xrd. fe-sem and eis. the results indicated a sharp increase in densification and conductivity for the system of ndcsi containing small amount of moo(3). it shows that ndcsi + 3moo(3) exhibited much higher relative density (rd = 96%), higher conductivity (sigma(t) = 1.25 x 10(-2) s cm(-1) at 600 degrees c) and lower activation energy (e(a) = 0.81 ev) compared with ndcsi and the other moo(3) doped-ndcsi samples. furthermore, moo(3) could be used as an effective sintering aid and a grain boundary scavenger for ndcsi system. and we obtained the optimal amount of the moo(3) is 3 mol%. crown copyright (c) 2011 published by elsevier masson sas. all rights reserved. |
