سنتز اكسيدهاي سرب A-PbO2 و B-PbO2 و بررسي عملكرد گرمايي آنها

The compounds lead oxides were prepared in this lab and its charaterization is made by X-Ray. The thermal properties is investigted by the Thermogravimetry method (TGA) in the range 25-600C. It is shown that this compounds decomposed at 600C in lead oxides a-PbO and /3-PbO. Investigation of the morphology of this compounds, Alpha-Pb02 and Beta-PbO2, is made by electron microscopy blow up to 5000.
