摘要

The thermal behavior of [Eu_2(BA)_6(dmbpy)_2] (BA=C_7H_5O_2~-, benzoate; dmbpy=C_(12)H_(12)N_2, 4, 4'-dimethyl-2,2'-bipyridine) and its kinetics were studied under the non-isothermal condition in a static air atmosphere by TG-DTG, IR and SEM methods. Thermal decomposition of [Eu_2(BA)_6(dmbpy)_2] occurred in four consecutive stages at T_p 232, 360, 455 and 495℃. The kinetic parameters were obtained from analysis of the TG-DTG curves by Achar and Madhusudanan-Krishnan-Ninan (MKN) methods. The most probable mechanisms for the first stage was suggested by comparing the kinetics parameters.
