Physical[ edit ] Droplet of solidified molten tin Tin is a soft, malleableductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the " tin cry " can be heard from the twinning of the crystals. The melting point is further lowered to It is a dull-gray powdery material with no common uses other than a few specialized semiconductor applications.
Alloying elements such as copper, antimony, bismuth, cadmium, and silver increase its hardness. Tin tends rather easily to form hard, brittle intermetallic phases, which are often undesirable.
It does not form wide solid solution ranges in other metals in general, and few elements have appreciable solid solubility in tin. Simple eutectic systems, however, occur with bismuthgalliumleadthallium and zinc. Tin can be highly polished and is used as a protective coat for other metals.
Isotopes of tin Tin has ten stable isotopeswith atomic masses ofthroughandthe greatest number of any element. Of these, the most abundant are Sn almost a third of all tinSn, and Sn, while the least abundant is Sn.
Tin, with its three common isotopes Sn, Sn and Sn, is among the easiest elements to detect and analyze by NMR spectroscopyand its chemical shifts are referenced against SnMe 4.
Tin also occurs in 29 unstable isotopes, encompassing all the remaining atomic masses from 99 to Apart from Snwith a half-life ofyears, all the radioisotopes have a half-life of less than a year.
The radioactive Sndiscovered inand Sn are one of the few nuclides with a " doubly magic " nucleus: The isotopes Sn through Sn also receive contributions from the r-process. Finally, the rarest proton-rich isotopes, Sn, Sn, and Sn, cannot be made in significant amounts in the s- or r-processes and are considered among the p-nucleiwhose origins are not well understood yet.
Some speculated mechanisms for their formation include proton capture as well as photodisintegrationalthough Sn might also be partially produced in the s-process, both directly, and as the daughter of long-lived In. It is not found in other branches of Indo-Europeanexcept by borrowing from Germanic e.
Tin sources and trade in ancient times Ceremonial giant bronze dirk of the Plougrescant-Ommerschans type, Plougrescant, France, — BC. Tin extraction and use can be dated to the beginnings of the Bronze Age around BC, when it was observed that copper objects formed of polymetallic ores with different metal contents had different physical properties.
Arsenical bronze objects appear first in the Near East where arsenic is commonly found in association with copper ore, but the health risks were quickly realized and the quest for sources of the much less hazardous tin ores began early in the Bronze Age.
Other forms of tin ores are less abundant sulfides such as stannite that require a more involved smelting process.
Cassiterite often accumulates in alluvial channels as placer deposits because it is harder, heavier, and more chemically resistant than the accompanying granite. Alluvial placer deposits could be easily collected and separated by methods similar to gold panning.Pest Analysis of Gucci in Malaysia; Pest Analysis of Gucci in Malaysia.
