Thermal decomposition of aluminum, iron and manganese complexes of urea

The thermal decomposition of the urea complexes Al(urea)6(NO3)3, Fe(urea)6(NO3)3 and Mn(urea)4Cl2 have been studied in air and argon by simultaneous recording of thermogravimetric (TG), differential thermal gravimetric (DTG) and differential thermal analysis (DTA) curves. The metal oxides formed by the decompositions have been identified by X-ray powder diffraction and decomposition stoichiometries have been proposed and...
