Red lead oxide, also known as minium or triplumbic tetroxide (Pb3O4), is a bright red to orange crystalline powder. It is a chemical compound composed of lead in its +4 oxidation state. Red lead oxide finds significant use as a pigment in various applications, including paints, primers, and ceramics, due to its intense color, good opacity, and resistance to acids and alkalis. It is also employed as a corrosion inhibitor for iron and steel and as a component in some types of glass. In addition to its industrial uses, red lead oxide has historical significance in traditional medicines, although its toxic nature limits such applications today. Due to its lead content, careful handling and disposal practices are necessary to prevent environmental contamination and health risks associated with lead exposure.
