metallic lead is a kind of metal particles made of lead, usually silver-gray, heavy and soft, with good ductility and easy to melt, cast, roll and extrude. The molecular formula of lead particles is Pb, melting point is 327.4℃, boiling point is 1740℃.
Chemical property
Lead particles can react with hot concentrated nitric acid, boiling concentrated hydrochloric acid or sulfuric acid, and will be eroded by pure water and weak organic acids under aerobic conditions. However, lead particles are resistant to hydrofluoric acid, tap water, salt water and solvents, and can gradually dissolve in alkali and form plumbite. In addition, the vapor of lead particles is toxic and should be used safely .
use
bullet making : Lead pellets are widely used in the making of bullets which, due to their high density, provide better stability and penetration when fired. In addition, lead absorbs and disperses the energy of the shot, reducing the damage caused to the target .
birdshot : In the sport of birdshot, lead pellets are used as birdshot to catch small birds and protect farmland and orchards 2.
fishing float : Lead particles can also be used to make fishing float, to help anglers maintain the balance of the float in the water, increase the chance of successful fishing .
alloy : Lead particles can be eutected with many metals into alloys for alloy manufacturing .
Storage and transportation
Lead pellets should be kept sealed and dry to prevent tarnishing by reacting with oxygen in the air
