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。
Reported the neodymium on the (NH4) 6 [C rM o5L aO24H6] .16H2O gas M0N preparation and electrical properties of the study. According to the TG-DTA test results, the temperature of rare-earth infiltration was determined to be 800 ℃. The XRF analysis showed that a slight amount of N d could penetrate into the bulk phase of heteropolyoxometalates, and the infiltration of N d Was 0.1347%. Comparing the XRD spectra of the compounds before and after diffusion, the diffraction peaks of the compounds before and after diffusion were significantly different, and the new compound M oN was confirmed. The conductivity of the samples before and after the expansion was tested by the four-electrode DC method. The results showed that the conductivity of the samples was significantly changed from 5.875 × 1-0 8S · cm-1 before infiltration to 1.030 × 102S.cm-1, an increase of 1.753 × 109 times.
