Uses and applications

What the substance is used for, by industry and function

Oxidizing agent, electrodes, lead-acid storage batteries, curing agent for polysulfide elastomers, textiles (mordant, discharge in dyeing with indigo), matches, explosives, analytical reagent.

Manufacturing rubber substitutes, with amorphous phosphorus as ignition surface for matches, pyrotechny, manufacturing pigments.

Curing agent for polysulfide, low-molecular weight butyl and polyisoprene, used as an oxidizer in the manufacture of dyes and to control burning in incendiary fuses.

Other applications of lead dioxide include antifriction compositions for plastic sliding bearings, ballistic modifers in high-energy propellants, electrodes for seawater electrolysis, filters for desulfurization of waste gases, and vulcanizing agents for butyl rubber puncture-sealing layers inside tires.

Industrial uses: Other, Oxidizing agent, Intermediate.

Consumer uses: Oxidizing agent, Other.

How it is made

Lead dioxide can be produced by anodic oxidation of solutions of lead salts or, commercially, by the oxidation of red lead, Pb3O4, in alkaline slurry with chlorine.

By adding bleaching powder to an alkaline solution of lead hydroxide.

Lab preparation from lead acetate and calcium hypochlorite ..., by hydrolysis of lead acetate...
