Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 – 80% lead oxide. Red lead (Pb 3 O 4) can also be added to the PbO formed by these methods, as it is more conductive. This is produced from PbO by roasting in a flow of air.
