High Quality Lead Ingot Lead Ingot 99.99 Metal Scrap

Lead is very stable in SO2, it hardly interacts with pure CO2, and the corrosion of ordinary water to lead is very slight. Lead is easy to dissolve in nitric acid, borofluoric acid, silicofluoric acid and acetic acid, but difficult to dissolve in sulfuric acid, hydrochloric acid and hydrofluoric acid at normal temperature. NH4OH solution or dilute NaOH solution with air can slowly dissolve lead. Lead can be dissolved in silver nitrate solution, and other nitrates and chlorides will corrode lead. Sulfates of potassium, sodium, iron, ammonia and potassium carbonate and cyanide solutions have no effect on lead.

Lead is initially oxidized to PbO2 during heating and melting, and then decomposed to PbO after heating, and Pb3O4 (i.e. lead) is generated when heating to 603-723K. Pb2O3 or Pb3O4 is easy to dissociate at high temperature to form stable PbO.
