摘　　要：Rare earth co-permeation of （NH4）3[CrMo6O24H6]·7H2O was reported and the conductivity of （NH4）3[CrMo6O24H6] was improved by 6.734×10^9 times. X-ray fluorescence spectrometry （XRF）, thermogravimetry-differential thermal analysis （TG-DTA）, X-ray diffraction （XRD） have been used to character （NH4）3[CrMo6O24H6]·7H2O and permeated sample. Experimental results showed that Nd could be permeated into the body of this sample and the XRD patterns showed great difference between （NH4）3[CrMo6O24H6]·7H2O and permeated sample. The structure of （NH4）3[CrMo6O24H6]·7H2O was destroyed and new compound MoN perhaps formed.Rare earth co-permeation of （NH4）3[CrMo6O24H6]·7H2O was reported and the conductivity of （NH4）3[CrMo6O24H6] was improved by 6.734×10^9 times.
