This post-transition silver and malleable metal, that not easily oxidizes to air and corrosion resistant, it’s used in many alloys and to coat other metals most vulnerable to corrosion. The tin is obtained mainly from cassiterite, a mineral in which is present in the oxide form, and from stannite. The tin has different uses though not vast. It is rarely used pure ( being too soft) but it is often alloyed with other metals. An important application of the tin, which absorbs about 35% of total consumption, is that of the protective surface tinning of ferrous alloys and of other metals. The tin-plating, which is carried out with tin or alloys containing also zinc, cadmium or nickel, can be performed either by immersion in the molten metal or electrolytically from alkaline solutions (is the most used process). Some organic salts are used in agriculture as fungicides and algaecides as in the rice fields. A lot of organic tin compounds are employed as stabilizers for plastics, in particular PVC. Even in organic synthesis applications have been found some organometallic compounds containing tin, such as dibutyltin oxide or tributyltin hydride, a reducing agent whose reduction reactions shall commence with radical mechanism.
