| Abstract: | The structures and phase transition of Al2(MoO4)3,Cr2(MoO4)3and Fe2(MoO4)3 materials have been studied by XRD,Raman spectroscopy and DSC.It is shown that Al2(MoO4)3,Cr2(MoO4)3and Fe2(MoO4)3 crystallize in monoclinic structure at room temperature and transform to orthorhombic phase at about 483 K,673 Kand 783 K,respectively.It is found that frequencies and relative intensities of the symmetric and asymmetric stretching vibrations of the MO4 tetraheda are obviously affected by A3 +cat-ions.They exhibit obviou... |
