Tin and Antimony – About Elements


Tin is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC.


Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.

Tin and Antimony – Applications


The largest single application of tin is in the manufacture of tinplate (steel sheet coated with tin), which accounts for approximately 40% of total world tin consumption. Tin bonds readily to iron and steel to prevent corrosion. Tin-plated steel containers are widely used for food preservation, and this forms a large part of the market for metallic tin. Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. The term is also widely used for the different process of coating a metal with solder before soldering. There are two processes for the tinning of the black plates: hot-dipping and electroplating.


The largest applications for metallic antimony are an alloy with lead and tin and the lead antimony plates in lead–acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain bearings. Antimony can be used in fire retardants for many commercial and domestic products. Antimony trichloride is used in the manufacturing flame-proofing compounds as well as paints, ceramic enamels, glass and pottery. Other uses include ball bearings and mixing with alloys with percentages ranging from 1 to 20 greatly increasing the hardness and mechanical strength of the lead. The capability to strengthen already strong alloys is its largest and most widespread use.
