Thermogravimetric (TG) studies of the reaction of lead oxide with lead sulphide

Abstract

In the paper, results of thermogravimetric study on reaction between lead oxide and lead sulphide, both loose and agglomerated samples. The research results showed that the reaction of lead sulphide with lead oxide is possible at temperatures exceeding 850 oC. Comparing the influence of the reaction temperature on the course of the TG curve and the percentage weight loss of the samples, it was found that the percentage weight loss of the samples increased with the increase of the temperature. This effect was observed both for samples introduced in loose form, as well as for the agglomerated one.
