| Abstract: | Zr1-xMxW2O8(M= Hf,Sn,Y) solid solutions are successfully synthesized by rapid solid-state reactions for the first time.The appropriate temperature and sintering time are 1523～1553 K and 30～60 min,respectively.Compared with traditional synthesis methods,this new synthetic method simplifies the production process and reduces the sintering time and energy consumption greatly.Powder XRD and Raman spectroscopic analyses reveal that the Zr1-xMxW2O8(M=Hf4+,Sn4+,Y3+) solid solutions are cubic ZrW2O8 type in crystal structure.Substitutions using equivalent and nonequivalent ions alter the properties of ZrW2O8 such as cell parameters,order-disorder phase transformation temperatures and thermal stability.Temperature dependent Raman spectroscopic studies demonstrate that the order-disorder phase transition temperature increases with increasing the content of Hf and decreases with increasing the content of Y and Sn. |
