What is Lead ?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Lead which has developed particularly rapidly in recent years. Do you know about Lead ?
The official answer: Lead is a metallic chemical element with the element symbol Pb, atomic number 82, atomic weight 207.2, is the largest non-radioactive element in atomic weight. Lead metal is a face-centered cubic crystal. [1]
Metal lead is a corrosion-resistant heavy non-ferrous metal material, lead has a low melting point, high corrosion resistance, X-ray and γ rays and other advantages are not easy to penetrate, good plasticity, etc., often processed into plates and pipes, used in chemical, cable, battery and radioactive protection and other industrial sectors
What’s the application of Lead ?
Lead is the raw material for the manufacture of 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. Because lead metal has excellent acid and alkali corrosion resistance, it is used in the manufacture of chemical and metallurgical equipment. Lead alloys are used as bearings, movable gold and solder, among others. Besides, lead has also opened up some new uses. Such as used as a stabilizer of asphalt to prolong the service life of the road surface; It is used to manufacture nuclear power plant shielding and nuclear waste storage tanks, high-power battery packs for adjusting loads in the electric power sector, and magnetohydrodynamic devices.
