The oxide particles are usually round or spherical m shape, and are all less than 60 pin in size with a mean diameter of34pm By contrast, ball mills yield an oxide with 60 70 wt.% PbO, an apparent density of g cm3 and an acid absorption of around 200 mg HZS04 per gram of oxide. The oxide particles are flat and nonuniform in shape.

A novel ultrafine leady oxide prepared from spent lead pastes for application as cathode of lead acid battery. The two predominant methods used to produce leady oxides are the "ballmill process" where lead is heated and oxidized by the tumbling action or the "Bartonpot" method where atomized liquid droplets are oxidized.

The aim of this research is to prepare leady oxide with high specific area for leadacid batteries by a new production process. Leady oxide is produced by a cementation reaction in wt% HCl solution using a pure aluminum or a magnesium rod as the oxide prepared in this process is much superior to Bartonpot or ballmill oxide in terms of physical characteristics.
