It is also widely used in optical, electrical, and electronic glasses, as well as in glazes for fine tableware. ... also used in rubber as a vulcanizing agent, in lead soaps employed as driers in varnishes, in high-temperature lubricants, as a neutralizing agent in organic syntheses, as a heat stabilizer in plastics, and as a starting material in the production of pigments.

Used in the production of capacitors, electrophotographic plates, transducers, and ferrimagnetic and ferromagnetic materials.

Industrial uses: Processing aids not otherwise specified, Other, Adsorbent, Intermediate, Chelating agent, Anti-slip agent, Flux agent.

Consumer uses: Lubricating agent, Alloys, Other, Anti-slip agent, Intermediate, Oxidizing agent.

How it is made

By oxidizing metallic lead in air. Various forms of lead and various temperatures from 500-1000 °C are used.

Produced commercially by the reaction of molten lead with air or oxygen in a furnace.

In the ball mill process, metallic lead balls are tumbled in air to produce a "leady" oxide, which typically contains 20 to 35 % free lead. The Barton pot process oxidizes droplets of molten lead at ca. 430 °C to produce either litharge or leady litharge.
