Phase diagram for the Na2O-PbO-H2O system at 130 degrees C
Liu, Yan1,2; Duan, Dongping1,2

A phase diagram of the Na2O-PbO-H2O system at 130 degrees C was studied using Schreinemakers's method, to provide fundamental data for producing PbO via hydrometallurgical process. In the phase diagram, saturated solubility of PbO has two maximum values vs the sodium hydroxide concentration in the solution. The equilibrium solid phases of lead oxide (PbO), sodium plumbite hydroxide (Na2O center dot PbO center dot H2O) and sodium hydroxide ( NaOH) were identified in the different alkali concentration regions, which is different from that at low temperature presented in literature.
