Red lead: understanding red lead in lead−acid batteries
Red lead (Pb 3 O 4), also known as minimum, trileadtetroxide or lead orthoplumbate, is normally a fine, dry, brilliant red colored solid usually used in the form of a powder can also be wetted and agglomerated into pellets. In contrast to other lead oxides, the lead atoms in red lead occur in two different oxidation states, i.e. Pb(II) and Pb(IV).
