Antimony is one of the chemical elements which have been known since the prehistoric times. It is a light grey color metalloid. Its symbol is the Eye of Horus, which is a sign of royal existence and good health. The name of this chemical element comes from a Latin expression meaning not alone. This chemical element is quite toxic, and even in small amounts it can be very harmful. It exists on the surface of earth in mirco amounts, and it is usually mined from minerals like antimony sulfide. Antimony is often alloys with lead and tin, to produce stronger and harder materials. It produces a large number of compounds which have a variety of applications. They are used as flame retardants, as well as for producing batteries, cable sheathing, pullets, printing machinery, diodes, matches, veterinary preparations, and other kinds of products.
