Red lead is a brilliant orange-red pigment. It is insoluble in water and ethanol, but dissolves in acetic acid or hot hydrochloric acid. Red lead is manufactured by heating lead monoxide in a reverberatory furnace in the presence of air at 450 – 500 0C until the desired composition is obtained.

Uses
Red Lead is used:

  • as a pigment in anticorrosion paints for steel surfaces.
  • in lead oxide pastes for tubular lead – acid batteries.
  • in ballistic modifiers for high-energy propellants.
  • in ceramic glazes for porcelain.
  • in lubricants for hot pressing metals.
  • in radiation-shielding foam coatings in clinical X-ray exposures.
  • in rubber adhesives for roadway joints.
