摘要

The thermal decomposition of the lanthanoid complexes of trifluoroacetic acid (Ln(CF_3COO)3-3H_2O; Ln = La-Lu) was studied by TG i and DTA methods. The Ln(CF_3COO)_3-3H_2O complexes decompose in several stages; first dehydrate to the anhydrous state, then followed by decomposition of the anhydrous salt to a stable product of LnF_3. From the endothermic and exothermic data of Ln(CF_3COO)_3-3H_2O 1 complexes, pyrolysis behavior of the complexes is classified into three groups: (1) La-Pr salts; (2) Nd-Gd salts; (3) Tb-Lu salts. It has been I shown that all the final decomposition products were found to result in the formation of LnF_3.
