摘要：
Hydrated heavier lanthanides(III) and yttrium(III) selenites, contend selenious acid were prepared. Thermogravimetry and differential thermogravimetry (TG-DTG), X-ray diffraction and other methods of analysis have been used in the characterization as well as in the study of the thermal decomposition of these compounds. The results led to the composition and thermal stability and also to interpretations concerning the thermal decomposition mechanism.
