Litharge, PbO, exists in a reddish alpha form up to 489 0C; it then transforms to a yellow beta form (massicot), which is stable at high temperatures. Lead oxides are produced industrially by thermal processes in which lead is directly oxidized with air. In the ball mill process, metallic lead balls are tumbled in air to produce a “leady” oxide, which typically contains 20 – 35% free lead. The Barton pot process oxidizes droplets of molten lead at ca. 430 0C to produce either litharge or leady litharge.

The most common and important metal alloyed with lead is antimony. Antimonial lead alloys usually contain from 1 to 6 percent antimony. Other components usually include tin, iron, copper, zinc, silver, arsenic, or traces of nickel. Because it has improved hardness and strength, antimonial lead has traditionally been known simply as hard lead

Lead sub oxide is also known as grey oxide because of its appearance. It is manufactured industrially from lead metal by oxidising it in the Ball Mill process. The molecular formula for lead sub-oxide is Pb.PbO Uses Lead sub-oxide is used in: Battery plates of lead-acid batteries, Liners of sulphuric acid tanks, Anode of electrolytic cell.Lead sub-oxide is available in 25 kg HDPE bags.
