| 摘 要： | F.Basile和M.A.Subramanian等人在常压高温下合成出变形的焦绿石化合物Er2Fe4/3W2/3O7,并用X射线粉末衍射法定出其结构属六方晶系。但对这种化合物的高温高压结构研究未见文献报导。我们在高压高温下进行了这种化合物的多形转变的研究。

| Abstract: | The polymorphic transformation of the compound Er2Fe4/3 W2/3O7 with hexagonal pyrochlore structure has been studied by high pressure and high temperature.It is found that the compound Er22Fe4/3 W2/3O7 has a phase transition from hexagonal to triclinic structure at 4.0GPa and 1200℃.Under this synthetic condition,the products of both synthesized directly from the mixture (Ⅰ) and from those hexagonal Er2Fe4/3 W2/3O7 (Ⅰ) have the same structures ( triclinic). |
