【摘要】 报道了钕对(NH4)6[C rM o5L aO24H6].16H2O气相渗制备M oN的方法及电性能研究。根据TG-DTA测试结果确定了稀土扩渗的温度为800℃,扩渗后的化合物经XRF分析测试表明,微量的N d可渗入到杂多金属氧酸盐的体相,N d的渗入量为0.1347%;对比扩渗前后化合物的XRD谱图发现,扩渗前后化合物的衍射峰有明显的不同,并证实生成新的化合物M oN。利用四电极直流法对扩渗前后样品的导电性能进行了测试,结果表明其导电性能发生了显著的变化,由渗前的5.875×1-0 8S.cm-1,提高到扩渗后1.030×102S.cm-1,提高了1.753×109倍。更多还原

【Abstract】 In this paper,Nd co-permeation of（NH₄）₆[CrMo₅ LaO₂₄H₆]·16H₂O has been reported for the first time.The co-permeation temperature is decided by TG-DTA and the XRF.The results of permeated sample indicate that Nd has permeated into the body of this compound.The XRD patterns show great different between（NH₄）₆[CrMo₅LaO₂₄H₆]·16H₂O and permeated one.The structure of（NH₄）₆[CrMo₅LaO₂₄H₆]·16H₂O was destroyed and new compound MoN perhaps formed.The permeated sample has been measured with fourelectrode method,the data imply that its conductivity improves 1.753×10⁹ times at room temperature,reaches to 1.030×10² S·cm^-1,which is a novel result.更多还原
