Lead is the raw material for making batteries, cables, bullets and ammunition, as well as an additive to gasoline. Lead compounds are used as raw materials for pigments, glass, plastics and rubber. Metal lead is widely used in manufacturing chemical and metallurgical equipment due to its excellent acid and alkali corrosion resistance. Lead alloys are used as bearings, movable type gold and solders. In addition, lead has also developed some new uses. For example, it can be used as a stabilizer of asphalt to prolong the service life of pavement; It is used to manufacture shielding and nuclear waste storage tanks for nuclear power plants, high-power battery packs for load adjustment of electric power departments, and magnetohydrodynamic devices.
