Applications 

Lead (II,IV) oxide, also called red lead, orange lead, minimum, is the inorganic compound with the formula Pb₃O₄. A bright red or orange solid, it is used as pigment, in the manufacture of batteries, and rust-proof primer paints. It is an example of a mixed valence compound, being composed of both Pb (II) and Pb (IV) in the ratio of two to one.  This 99.99% high purity lead oxide powder is an ideal precursor material for making high performance optical glass and crystal materials. 

Lead (II,IV) oxide has a tetragonal crystal structure at room temperature, which then transforms to an orthorhombic (Pearson symbol oP28, Space group Pbam, No. 55) form at temperature 170 K (−103 °C). This phase transition only changes the symmetry of the crystal and slightly modifies the interatomic distances and angles.
