Brief description |
| |
The melting point of antimony is 630.74°C, boiling point is 1950°C, specific gravity is 6.691 (at 20°C), with a valence of 0, -3, +3, or +5. Two allotropic forms of antimony exist: the usual stable metallic form and the amorphous gray form. Metallic antimony is extremely brittle. It is a bluish white metal with a flaky crystalline texture and metallic luster. It is not oxidized by air at room temperature. However, it will burn brilliantly when heated, releasing white Sb2O3 fumes. It is a poor heat or electrical conductor. Antimony metal has a hardness of 3 to 3.5.

Uses of Antinomy |
| |
Antimony is widely used in alloying to increase hardness and mechanical strength. Antimony is used in the semiconductor industry for infrared detectors, Hall-effect devices, and diodes. The metal and its compounds also used in batteries, bullets, cable sheathing, flame-proofing compounds, glass, ceramics, paints, and pottery. Tartar emetic has been used in medicine. Antimony and many of its compounds are toxic.
