Lead as the metal is used in:
• Storage batteries.
• Solders and bearing metals.
• Cable coverings for telephone line and power lines to prevent mechanical injury.
• Plumbing as pipes, fittings, roofing, storage tanks, gutters, flashing.
• Collapsible piping.
• Automotive fuel tanks for the protection against corrosion (Terneplate).
• Machine bearings (Hoyt metal), railway car bearings (lining metal) and locomotive crosshead linings (Dandelion metal).
• Lead tetraethyl manufacturing.
• As a sound and vibration absorber.
• Radiation shielding, implemented around X-ray equipment and nuclear reactors – in the form of shielding cements, neoprene-lead fabric, ceramic mortars, paints (Chemtree 82) and other plastic composite structures.
• Toys, small castable articles.
• As an alloying element to improve specific mechanical properties such as tensile strength, elongation, hardness.
Lead compounds are used for:
• Pigments for paints e.g. 2PbCO3.Pb(OH)2 or white lead, PbCrO4 or yellow chrome, Pb3O4 or red lead, PbWO4 or lead tungstate (a yellow pigment).
• Lead meta-silicate (PbSiO3) a white crystal used for glazing ceramics and fireproofing textiles.
• Lead oxide is used in the production of fine crystal glass and flint glass, for achromatic lenses, it is also used as a filler in rubbers.
• Lead sulphide (PbS), may be used as a filler in missiles, due to its sensitivity to heat rays.
• Lead dioxide or lead peroxide (PbO2), a brown powder, is used in matches, dyes, and pyrotechnics, as a mordant and as an oxidising agent.
