Shouldn’t tin’s atomic symbol be Tn instead of Sn? Actually, Sn is short for the Latin word for tin, stannum.
When tin is bent at room temperature, it makes a high-pitched creaking sound known as the „tin cry” caused by the deformation of tin crystals.
There are many important uses for tin. Most is used to produce tinplate, or steel coated with tin which is used for food packaging. Tin and tin alloys are used also for solder, especially in the electronics industry; approximately 50% of the world supply of tin is used in solder, although this number has been declining in recent years. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.
Inorganic compounds of tin are used in ceramics and glazes. Organic compounds of tin are used in plastics, wood preservatives, pesticides and in fire retardants.
The supply of tin derives from two sources: primary production (mining) and secondary production (recycling). Mining provides most of the supply, although the United States.
Tin produced by smelting concentrate or slag commonly contains metallic impurities which must be removed by refining before the tin is marketed. Refining techniques include heat treatment or electrolytic processes.The materials are then heated to a temperature of about 2,550 degrees Fahrenheit. Sometimes blast furnace slags – residual products from heating tin – form in the furnace. These products get heated again in a second furnace to recover additional tin.
