Thermal Behavior Of Alkaline Lead Carbonate, A Study Of Thermogravimetry And Differential Scanning Calorimetry

S.A.A.Sajadi, and A.Alamolhoda

The compound alkaline lead carbonate 3PbCO3 .2Pb(OH)2 was prepared in our laboratory. The Thermal behavior of this compound was studied using both techniques of thermogravimetery and differential scanning calorimetery under O2 gas atmosphere from 25 to 600°C. The identity of products at different stages were confirmed by XRD technique. Results obtained using both techniques support same decomposition stages for this compound. Three distinct energy changes takes place, two endothermic and one exothermic in DSC results. The amount of ΔH for each peak is reported. ï›™ 2006 Trade Science Inc. - INDIA
