Zirconium tungsten oxyfluoride,ZrWO_4F_2,was firstly synthesized with the pr ecursor route.The composition of the compound was determined by combi ning the results of ICP and XPS.The in dexed powder X-ray diffraction pattern of this compound indicates t hat it is a pure phase,orthorhombic c rystal system,space group D 22 =P2 1 22and a=15.32(2)*!,b=13.877(7)*!,c=8.42(2)*!.Combining the results of the DTA-T GA curves from room temperature to 700℃and XRD patterns in different temperatures the mechanism was revealed during the solid precursor(1)been heated to 700℃.The zirconium tu ngsten oxyfluoride was considered t o be a metastable com-pound.The ascertaining of annealin g time and temperature is the key of handling.
Zirconium tungsten oxyfluoride, ZrWO_4F_2, was gained synthesized with the pr ecursor route. The composition of the compound was determined by combi ning the results of ICP and XPS. In in dexed powder X-ray diffraction pattern of this compound indicates t hat it is a pure phase, orthorhombic cysystal system, space group D 22 = P2 1 22 and a = 15.32 (2) * !, b = 13.877 (7) * !, c = 8.42 (2) * !. Combining the results of the DTA- T GA curves from room temperature to 700 ° C and XRD patterns in different temperatures the mechanism was revealed during the solid precursor (1) been heated to 700 ° C. The zirconium tu ngsten oxyfluoride was considered to be metastable com-pound. Ascertaining of annealin g time and temperature is the key of handling.
