摘要
分别用固相反应法和凝胶注方法制备了固体氧化物燃料电池(SOFCs)阳极用La_xSr_(1-x)Cr_yTi_(1-y)O_3(LSCT)系列化合物,用SEM、XRD等手段研究了其显微结构,并测试了该材料的电导率,综合以上三项对La_xSr_(1-x)Cr_yTi_(1-y)O_3系列用作固体氧化物燃料电池阳极材料的性能进行评价,筛选了配方,并对制备工艺进行了讨论。
Sr and Ti co-doped LaCrO3 （LaxSr1-xCryTi1-yO3） powders were synthesized from carbonate and oxides based on the principle of solid state reaction and gel-casting. XRD patterns indicated the perovskite structure was formed without any second phases when sintering at 1450 ℃ for 6 h by gel-casting, which was lower than by solid state reaction at 100 ℃. The total electrical conductivity was greatly depended on the ingredient, and reached the maximum when x=0.2, y=0.3.
