Lead Oxide
The Barton pot method is more productive, while the leady oxide produced by the Ball mill method is more reactive. An overview of the basic characteristics of leady oxides (crystal modification, chemical composition, water and H 2 SO 4 absorption, specific density, particle size distribution and stability of the leady oxide) is presented.

AP-42, CH 12.16: Lead Oxide And Pigment Production
12.16 Lead Oxide And Pigment Production. Lead oxide is a general term and can be either lead monoxide or "litharge" (PbO); lead tetroxide or "red lead" (Pb3O4); or black or "gray" oxide which is a mixture of 70 percent lead monoxide and 30 percent metallic lead. Black lead is made for specific use in the manufacture of lead acid storage batteries.
