The studies of IR and XRD indicate that the compound has the Keggin structure. The rare earth chemical thermal diffusion of the complex also was studied. The results show that the rare earth element Gd can permeate into the surface, interface and the body cavity of the prepared material. The results of TG-DTA show that the stable temperature is improved and the conductivity of the permeated sample is 3.05 S·cm -1, which is 4.67×106 times higher than that of the parent K_7[BNi(OH_2)W_ 11O_ 39]·11H_2O.展开更多
