Abstract
The hydrated basis carbonates of lanthanides and yttrium were prepared by precipitation from homogeneous solution via the hydrolysis of urea , without the addition of an auxiliary anion. Thermogravimetry, deriva tive thermogravimetry (TG-DTG), and differential thermal analysis (DTA ) have been used in the study of these compounds in CO2 atmosphere. Th e results lead to the composition and thermal stability of the studied compounds, and also to a comparative study with reported results in a ir atmosphere.
