by evaporation of PbO in the approximately temperature
range of 1100˚C to 1200˚C. We are not able to consider
these two phenomenons separately because these two
reactions overlap each other.
4. Conclusions
It was clearly stated that the final product consists only
of α- and β-PbO, which was a good result. The chemical
analysis showed no impurities. The thermal investiga-
tions of PbSO4 by TG method showed that under air at-
mosphere the compound decomposes to α- and β-PbO.
Since PbO does not contain impurities, one can reuse in
the industry. Lead sulfate can be converted to PbO in
industry which is an economical procedure.
