Trilead tetroxide

Trilead tetroxide, Pb304, red lead and other intermediate phases, e.g. Pb70i, and Pb203 are formed by heating PbO or Pb02- Uses... 

Lead contamination of soil is a result of introduction of trilead tetroxide, present in petrol and combustion gas. Lead may also be released from incorrectly enameled plates and old plumbing (Galal-Gorchev, 1993). Lead may accumulate in vegetables, fruit, and herbs. About 50% of the lead intake of children and 20% of intake by adults is absorbed from the gastrointestinal tract. It is distributed through the human body via the bloodstream and is...

Corrosion occurs more rapidly when there is a dissolved salt, higher acidity or air pollution, because dissolved CO2 produces and HCO3" ions. One way to prevent the corrosion of iron is to coat it with special paints containing potassium dichromate (K2Cr202) and trilead tetroxide (Pb304).

Trilead tetroxide, red lead, minium, Pb304, is mixed with linseed oil and used principally as a paint to prevent the rusting of steel, particularly to objects exposed to the weather, such as ships, bridges and agricultural machinery. It is also used for making lead glass and special lead jointing compounds.
