摘要

The modeling of the defect structure of LnMeO_(3+δ) (Me=Pr, Nd) has been made based on the results obtained by high temperature TGA. It was shown that results are very sensitive to the Ln:Mn ratio which can change during the preparation procedure. The homogeneity range in the praseodymium manganite was found to exist in the metal sublattices. The Pr:Mn ratio can vary from 0.85:1 to 1:0.9 at 1100℃ in air.
