Red lead: understanding red lead in lead−acid batteries
Red lead is sometimes confused with the tetragonal form of leady oxide (α-PbO), which also has a red color, but actually is the raw material for the production of red lead. Red lead forms through an oxidation process when α-PbO is heated to around 450–500 C, but decomposes to yellow litharge (β-PbO, orthorombic) when temperatures …
