Praseodymium Chemistry-Heated Diffused Permeation is used to treat K 7 MgBW 11 O 39 for the first time.ICP,IR,XRD,TG-DTA,have been used to characterize K 7 MgBW 11 O 39 ·15H 2 O and treated sample,indicating that Pr can be permeated into the body of this sample.The results of AC impedance s pectra and DC four-probe show that the value of conductivity is 10 4 times higher than that of sample befo re permeation at room temperature.At the range of 301～576K,the conductivity of permeated sample almost keep constant a nd its thermal stability improved mo re than 150K,which imply that this mate rial is promising.
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 . 15H(2)O 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 10(4) times higher than that of sample before permeation at room temperature. At the range of 301 similar to 576K, the conductivity of permeated sample almost keep constant and its thermal stability improved more than 150K, which imply that this material is promising.
