名称来源 Named after Etruscan god, Tinia; symbol from Latin: stannum (tin).
发现者 Known to the ancients.

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.

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.
