Thermal Behavior of Alkaline Lead Acetate, a Study of Thermogravimetry and Di erential Scanning Calorimetry

The compound, alkaline lead acetate, Pb(CH3COO)2: PbO:H2O (ALA), was purchased from the Fluka Company. The X-ray di raction lm and SEM electron microgaph of this compound were obtained and reported in this paper for the rst time. The thermal behavior of alkaline lead acetate (ALA) was studied using thermogravimetery (TGA) and Di erential Scanning Calorimetery (DSC) techniques under an O2 gas atmosphere from 25 to 600C. Four distinct energy changes associated with weight changes were observed, all of them being exothermic in the DSC results. The amount of
H for each peak is reported.
