摘要: 合成并表征了一系列化合物Al2Mo3-xWxO12 x=0,0.5,1.0,1.5和2.0的化合物是以单斜晶系Al2(MoO4)3为基质的化合物和固溶体,空间群为P21/a;x=2.5和3.0的标题化合物是以正交晶系Al2(WO4)3为基质的固溶体和化合物,空间群为Pbcn.利用粉末X射线衍射图谱全谱拟合的方法精修了x=0,0.5,1.0,1.5,2.0的标题化合物的结构,讨论其相变机理.

关键词: Al2Mo3-xWxO12, 合成, 结构的精修

Abstract: The title compounds were synthesized and characterized as P21/a space group in monoclinic phase for x=0, 0.5, 1.0, 1.5, 2.0 and Pbcn space group in orthohombic phase for x=2.5, 3.0. The structure refinments were success for x=0, 0.5, 1.0, 1.5, 2.0 using laboratory Xray data. The preliminary interpretation of the phase transition was discussed on the basis of the structural parameters.
