Lead content

Lead (Pb) is a high-density, soft blue-gray metal with a melting point of 327°C and a boiling point of 1740°C. [1] When the temperature exceeds 400°C, a large amount of lead vapor escapes and rapidly oxidizes into lead oxide fumes in the air. Common lead-containing substances include PbO, Pb2O3, Pb3O4, Pb(OH)2·2PbCO3, and lead sulfate (PbSO4).
