Pyromorphite growth on lead sulfide surfaces PubMed

Through cyclic voltammetry we show that the presence of phosphate also partially passivates the surface of the galena to oxidation We propose two possibilities for the mechanism of passivation one is that pyromorphite nucleation inhibits the retreat of steps and the second is that adsorbed phosphate stabilizes a lead terminated surface structure by coordinating lead and slowing its
