Abstract: Praseodymium Chemistry-Heated Diffused Permeation is used to treat K₇MgBW₁₁O₃₉ for the first time. ICP， IR， XRD， TG-DTA， have been used to characterize K₇MgBW₁₁O₃₉·15H₂O and treated sample， indicating that Pr can be permeated into the body of this sample. The results of AC impedance spectra and DC four-probe show that the value of conductivity is 10⁴ times higher than that of sample before permeation at room temperature. At the range of 301～576K，the conductivity of permeated sample almost keep constant and its thermal stability improved more than 150K， which imply that this material is promising.

Keywords: POMs Pr heated diffused permeation conductivity
