Antimony

Antimony is a chemical element with the symbol Sb and atomic number 51. It is a silvery gray, brittle, semi-metal that is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony is primarily produced from stibnite, which is mined in China, Bolivia, and South Africa. Antimony has a number of important uses. Its most significant use is as a flame retardant in materials such as plastics, textiles, and e...

Antimony is a chemical element with the symbol Sb and atomic number 51. It is a silvery gray, brittle, semi-metal that is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony is primarily produced from stibnite, which is mined in China, Bolivia, and South Africa.

Antimony has a number of important uses. Its most significant use is as a flame retardant in materials such as plastics, textiles, and electronics. It is also used in alloys, where it increases the hardness and strength of the metal. In addition, antimony is used in the production of batteries and glass, and as a catalyst in the production of polyethylene terephthalate (PET) plastic.

Antimony is typically produced through a process known as smelting, in which the sulfide mineral stibnite is heated in the presence of oxygen to convert it into elemental antimony. The antimony is then separated from the resulting slag and purified through a series of additional processes. Some antimony is also produced as a byproduct of lead and copper smelting.
