Tin ingot

详情

This silvery, malleable post-transition metal is not easily oxidized in air and is used to coat other metals to prevent corrosion. The first alloy, used in large scale since ***0 BC, was bronze, an alloy of tin and copper. After **0 BC pure metallic tin was produced. Pewter, which is an alloy of *5–*0% tin with the remainder commonly consisting of copper, antimony and lead, was used for flatware from the Bronze Age until the *0th century. In modern times tin is used in many alloys, most notably tin/lead soft solders, typically containing *0% or more of tin. Another large application for tin is corrosion-resistant tin plating of steel. Because of its low toxicity, tin-plated metal is also used for food packaging, giving the name to tin cans, which are made mostly of steel.
Tin is a chemical element with symbol Sn (for Latin: stannum) and atomic number *0. It is a main group metal in group *4 of the periodic table. Tin shows chemical similarity to both neighboring group**4 elements, germanium and lead and has two possible oxidation states, *2 and the slightly more stable *4. Tin is the *9th most abundant element and has, with *0 stable isotopes, the largest number of stable isotopes in the periodic table. Tin is obtained chiefly from the mineral cassiterite, where it occurs as tin dioxide, SnO2.
 
Physical properties:

Tin is a malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the tin cry can be heard due to the twinning of the crystals.[4] Tin melts at a low temperature of about **2 °C (**9.6 °F), which is further reduced to **7.3 °C (**1 °F) for **-nm particles.
 
Chemical properties:
 
Tin resists corrosion from water but can be attacked by acids and alkalis. Tin can be highly polished and is used as a protective coat for other metals. In this case the formation of a protective oxide layer is used to prevent further oxidation. This oxide layer forms on pewter and other tin alloys. Tin acts as a catalyst when oxygen is in solution and helps accelerate chemical attack.
