Tin is a post-transition metal in group 14, known for its low melting point, resistance to ordinary corrosion, and ability to form useful alloys and coatings. It occurs chiefly as cassiterite, a tin dioxide mineral, and has been worked since antiquity, especially in bronze. Chemically it is less reactive than many base metals but readily forms compounds in the +2 and +4 oxidation states, with organotin chemistry being especially important and sometimes hazardous.
Ordinary tin is composed of nine stable isotopes; 18 unstable isotopes are also known. Ordinary tin is a silver-white metal, is malleable, somewhat ductile, and has a highly crystalline structure. Due to the breaking of these crystals, a "tin cry" is heard when a bar is bent.
The name derives from the Anglo-Saxon tin of unknown origin. The symbol Sn is derived from Latin stannum for alloys containing lead. The element was known in prehistoric times.
Archaeological evidence suggests that people have been using tin for at least 5500 years. Tin is primarily obtained from the mineral cassiterite (SnO2) and is extracted by roasting cassiterite in a furnace with carbon. Tin makes up only about 0.001% of the earth's crust and is chiefly mined in Malaysia. Two allotropes of tin occur near room temperature. The first form of tin is called gray tin and is stable at temperatures below 13.2°C (55.76°F). There are few, if any, uses for gray tin. At temperatures above 13.2°C, gray tin slowly turns into tin's second form, white tin. White tin is the normal form of the metal and has many uses. Unfortunately, white tin will turn into gray tin if its temperature falls below 13.2°C. This change can be prevented if small amounts of antimony or bismuth are added to white tin.
The Latin word for tin is stannum. Known to the ancients.
Pure tin is a soft, silvery-white metal with a bright metallic luster. It is malleable at room temperature and melts at a relatively low temperature for a metal. Below about 13.2 °C, white tin can slowly transform to brittle gray tin under favorable conditions, a phenomenon known as tin pest.
Tin is used mainly as a protective coating on steel for food cans and other corrosion-resistant sheet products. It is an important constituent of solders, especially lead-free solders based on tin with silver, copper, antimony, or bismuth additions. Tin is also used in bronze, bearing metals, pewter, and some specialty alloys. Indium tin oxide, a mixed oxide material, is widely used as a transparent conducting coating in displays and touch panels.
Tin resists corrosion and is used as a protective coating on other metals. Tin cans are probably the most familiar example of this application. A tin can is actually made from steel. A thin layer of tin is applied to the inside and outside of the can to keep the steel from rusting. Once widely used, tin cans have largely been replaced with plastic and aluminum containers.
Tin is used in the Pilkington process to produce window glass. In the Pilkington process, molten glass is poured onto a pool of molten tin. The glass floats on the surface of the tin and cools, forming solid glass with flat, parallel surfaces. Most of the window glass produced today is made this way.
Tin is used to form many useful alloys. Bronze is an alloy of tin and copper. Tin and lead are alloyed to make pewter and solder. An alloy of tin and niobium is used to make superconductive wire. Type metal, fusible metal, bell metal and Babbitt metal are other examples of tin alloys.
Tin salts can be sprayed onto glass to make electrically conductive coatings. These can then be used to make panel lighting and frost-free windshields. Stannous fluoride (SnF2) is used in some types of toothpaste.
Isotopes in Earth/Planetary Science
Molecules, atoms, and ions of the stable isotopes of tin possess slightly different physical and chemical properties, and they commonly will be fractionated during physical, chemical, and biological processes, giving rise to variations in isotopic abundances and in atomic weights. There are measureable variations in the isotopic abundances of tin in natural terrestrial materials (Fig. IUPAC.50.1) [366] E. Yamazaki, S. Nakai, T. Yokoyama, S. Ishihara, H. Tang. Geochem. J.47, 21 (2013)..
Isotopes in Medicine
117mSn (with a half-life of 14 days) DTPA is routinely used for diagnostic bone imaging and for the treatment of bone pain caused by the spread of cancer to bones. The m in the superscript of 117mSn indicates a metastable state of the isotope. By using 117mSn DTPA, marrow toxicity can be reduced, and the therapeutic efficacy of using radionuclides is maintained [367] A. Bishayee, D. V. Rao, S. C. Srivastava, L. G. Bouchet, W. E. Bolch, R. W. Howell. J. Nucl. Med.41, 2043 (2000).. 117mSn is a promising radionuclide for therapeutic applications because the radionuclide decays in a way that causes less damage to healthy tissues and bone marrow than other available treatments. These properties of 117mSn make it useful for the treatment of inflammatory synovial disease (i.e. rheumatoid arthritis) [368] S. C. Srivastava. Braz. Arch. Biol. Technol.50, 49 (2007)..
Isotopes Used as a Source of Radioactive Isotope(s)
112Sn is used to produce the radioisotope 113Sn (with a half-life of 115 days) via the reaction 112Sn (n, γ) 113Sn. This is used for n(113Sn)/n(113mIn) generators for the elution (extracting one material from another) of 113mIn (with a half-life of 1.66 h) as chloride for blood pool imaging. The m the superscript of 113mIn indicates a metastable state of the isotope. 117mSn is a medical radioisotope that can be produced using 116Sn and 117Sn [369] B. Ponsard, S. C. Srivastava, L. F. Mausner, F. F. Knapp, M. A. Garland, S. Mirzadeh. Appl. Radiat. Isot.67 1158 (2009)..
Tin commonly forms Sn²⁺ and Sn⁴⁺ compounds. Tin dioxide, SnO₂, is the principal ore mineral and is also used in ceramics, glass polishing, and some conductive or catalytic materials. Tin(II) chloride, SnCl₂, is a reducing agent and a reagent in plating and dyeing processes, while tin(IV) chloride, SnCl₄, is a volatile Lewis acid used in chemical synthesis and surface treatment. Organotin compounds contain Sn–C bonds; some, such as tributyltin oxide, C₂₄H₅₄OSn₂, were formerly used as biocides but are tightly restricted because of toxicity.
The element has two allotropic forms at normal pressure. On warming, gray, or alpha tin, with a cubic structure, changes at 13.2°C into white, or beta tin, the ordinary form of the metal. White tin has a tetragonal structure. When tin is cooled below 13.2°C, it changes slowly from white to gray. This change is affected by impurities such as aluminum and zinc, and can be prevented by small additions of antimony or bismuth. This change from the alpha to beta form is called the tin pest. There are few if any uses for gray tin. Tin takes a high polish and is used to coat other metals to prevent corrosion or other chemical action. Such tin plate over steel is used in the so-called tin can for preserving food.
Alloys of tin are very important. Soft solder, type metal, fusible metal, pewter, bronze, bell metal, Babbitt metal, White metal, die casting alloy, and phosphor bronze are some of the important alloys using tin.
Tin resists distilled sea and soft tap water, but is attacked by strong acids, alkalis, and acid salts. Oxygen in solution accelerates the attack. When heated in air, tin forms Sn2, which is feebly acid, forming stannate salts with basic oxides. The most important salt is the chloride, which is used as a reducing agent and as a mordant in calico printing. Tin salts sprayed onto glass are used to produce electrically conductive coatings. These have been used for panel lighting and for frost-free windshields. Most window glass is now made by floating molten glass on molten tin (float glass) to produce a flat surface (Pilkington process).
Also interesting is a crystalline tin-niobium alloy that is superconductive at very low temperatures. This promises to be important in the construction of superconductive magnets that generate enormous field strengths but use practically no power. Such magnets, made of tin-niobium wire, weigh only a few pounds and produce magnetic fields that, when started with a small battery, are comparable to that of a 100 ton electromagnet operated continuously with a large power supply.
See more information at the Tin compound page.
Metallic tin has low acute toxicity and is commonly used in food-contact coatings, although excessive intake of soluble tin salts can irritate the gastrointestinal tract. Tin dusts and fumes from melting, soldering, or industrial processing can present inhalation hazards. Organotin compounds vary widely in toxicity; several are potent neurotoxic or endocrine-disrupting substances and require strict control. Radioactive tin isotopes are mainly research or fission-product concerns, not a property of natural tin as a whole.
The small amount of tin found in canned foods is quite harmless. The agreed limit of tin content in U.S. foods is 300 mg/kg. The trialkyl and triaryl tin compounds are used as biocides and must be handled carefully.
Tin is present in the crust mostly in resistant oxide minerals, especially cassiterite, and is not highly mobile under many natural surface conditions. Mining and smelting can release tin-bearing particulates and associated metals, depending on the ore and waste management. Inorganic tin compounds usually show limited bioavailability compared with many organotin compounds. Persistent organotin residues in sediments have been a major concern in harbors and shipyard areas where antifouling paints were used.
Tin is produced chiefly by mining cassiterite from hard-rock and alluvial deposits, followed by concentration, smelting, and refining. Supply is geographically concentrated in a limited number of producing regions, and some production comes from small-scale or artisanal mining. Demand is dominated by solder, tinplate, chemicals, and alloy uses. Recycling is important, especially from solder-bearing electronic scrap and tinplate residues, but recovery can be technically diffuse because tin is often present in thin coatings or complex assemblies. Substitution is possible in some coatings and solders, but performance, food-contact requirements, and processing temperatures limit replacements.
Tin is found chiefly in cassiterite (SnO2). Most of the world's supply comes from Malaya, Bolivia, Indonesia, Zaire, Thailand, and Nigeria. The U.S. produces almost none, although occurrences have been found in Alaska and California. Tin is obtained by reducing the ore with coal in a reverberatory furnace.
Tin is a relatively heavy element made mainly by neutron-capture nucleosynthesis in earlier generations of stars. It is far less abundant cosmically than lighter rock-forming elements, but it is present in meteorites and planetary materials at trace levels. In differentiated planets, tin tends to behave as a lithophile to mildly chalcophile element, concentrating in crustal minerals and some sulfide-associated systems rather than forming abundant native metal.
- Tin has ten stable isotopes, more than any other element.
- The symbol Sn comes from the Latin name stannum.
- The crackling sound of bent tin is called tin cry and comes from crystal deformation.
- Tin pest is promoted by low temperature and can be inhibited by alloying additions.
- Most modern food cans are steel cans with a very thin tin coating, not solid tin.
- Cassiterite is dense, which makes gravity separation useful in ore concentration.

Sources
Sources of this element.
Tin is found chiefly in cassiterite (SnO2). Most of the world's supply comes from Malaya, Bolivia, Indonesia, Zaire, Thailand, and Nigeria. The U.S. produces almost none, although occurrences have been found in Alaska and California. Tin is obtained by reducing the ore with coal in a reverberatory furnace.
