USE：Antimony is a semi-metallic chemical element in Group Va of the periodic table; atomic number 51; atomic mass 121.75; melting point ca 630.7 C; boiling point at  1,750 C; specific gravity 6.69 at 20 C; valence 0, +3, -3, or +5.; electronic config. [Kr]4d10 5s2 5p3. There are four allotropic forms. The common and stable form is a very brittle, blue-white, hexagonal mineral and has a rhombohedral crystalline structure. Yellow and black antimony shows the properties of unstable non-metals. It is a poor conductor of heat and electricity and is easily powdered to be used by itself.  The chief ore of antimony is stibnite (Sb2S3, antimony trisulfide) which is produced in China and covers three-fourths of the world's mined antimony. It is also found in isomorphous mixture with arsenic, as allemonite. Substantial quantity of antimony are produced as a by-product in the smelting of base metal ores also. The pure antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron. Antimony is soluble in hot nitric or sulfuric acid and reacts with oxidizing acids and halogens (fluorine, chlorine, or bromine). It does not react with water at room temperature but will ignite and burn in air at higher temperatures. To make stronger, brittle, solidification expanded and low melting point metals, antimony is mixed with other metals such as lead and zinc alloys which are used in solder, bearings, castings, safety matches, and as a red pigment in paint as well as as a hardner in lead storage batteries, the most important use of antimony metal. Antimony is being the important element in the semiconductor industry to make diodes, infrared detectors, and Hall-effect devices. Antimony tartrate was used as an emetic and expectorant, to produce sweating, and treat people infected with parasites, but is poisonous and has toxic side effects. Mined antimony is combined with oxygen to form antimony oxide, one of the most important antimony compounds. Antimony oxide is a white rhombic crystals; melting at 656°C; insoluble in water; powerful reducing agent. Most antimony oxide produced is added to textiles and plastics as fire retardant. It is also used in paints, ceramics and fireworks, and as enamels for plastics, metal and glass. Antimony oxides don't react as flame retardants directly. They are used as synergists to enhance the activity of halogenated flame retardants by stepwise releasing the halogenated radicals to retard gas phase chain reaction of flame spread. There are many antimony compounds for industrial use
