Tin Powder

Tin is a chemical element with the symbol Sn (from the Latin: estannum) and the atomic number 50. It is a metal after the transition in group 14 of the periodic table of the elements. It is obtained mainly from mineral cassiterite, which contains tin oxide, SnO2. Tin shows a chemical resemblance with its two neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and +4 slightly more stable. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magical number of protons. It has two main allotropes: at room temperature, the stable allotrope is β-tin, a silvery white malleable metal, but at low temperatures it becomes the less dense α-tin gray, which has the cubic structure of the diamond. The metallic tin does not easily oxidize in the air.

The first tin alloy used on a large scale was bronze, made of tin and copper, from 3000 BC. After 600 BC, a pure metal tin was produced. Tin, which is an alloy of 85% to 90% tin, and the remainder commonly made of copper, antimony and lead has been used for silverware from the Bronze Age to the 20th century. In modern times, tin is used in many alloys, particularly in soft tin / lead solder, which is typically 60% or more tin, and in the production of transparent and electrically conductive films of indium and tin oxide in optoelectronic applications . Another important application for tin is tinning in corrosion resistant steel. Due to the low toxicity of inorganic tin, tin-plated steel is widely used for packaging foods such as cans. However, some organotin compounds may be as toxic as cyanide.
