研究制备了分散均匀的纳米WNiFe复合盐.以化学共沉淀法制备的盐在600℃下氧化,可得WNiFe复合氧化物, 检测分析显示WNiFe复合氧化物粉的晶粒直径XRDd为36 nm,WNiFe复合氧化物粉的颗粒粒径BETd为98 nm;从SEM图分析看出该复合氧化物粉颗粒团聚性低,压坯EDXS的表面电子图像和元素面分布图显示该复合氧化物粉中W、Ni、Fe元素分布状态是高度均匀分布.

WNiFe composite oxides nanopowder has been prepared from finely grained tungstate synthesized by chemical coprecipitation and oxided at 600℃. The characteristics of the powder were studied and measured by EDXS, XRD, SEM and TEM. Fsss size and special surface area were also analyzed. The results show the average grain size of the composite oxides nanopowder was 36nm(XRDd) and the particle size was 98nm(BETd). The particle morphology from SEM, TEM and BETs, XRDd indicates the poor agglomeration of the powder and the dispersion of W, Ni and Fe elements in the nanopowder from EDXS maps was highly homogeneous
