What is Antimony?
- Antimony is a semi-metallic chemical element with an atomic number 51 and symbol Sb in the Periodic Table.
- Latin name of Antimony is Stibium. It is generally found in two forms namely metallic form and non-metallic form.
- Antimony compounds are used since ancient times as a component in cosmetics.
- It is naturally found in Earth’s crust in the ores of valentinite and stibnite.
Uses of Antimony
- Pure antimony is used in the manufacturing of certain semiconductors like infrared detectors and diodes.
- It is used to harden lead and increase its durability.
- Batteries consist of antimony for smooth functioning.
- It is also used to make small arms & bullets.
- It is a very good flame retardant.
Properties of Antimony
- The metallic form appears in a bright silver colour brittle and non-metallic form will appear as the grey powder.
- It is a weak conductor of electricity and heat. The special feature of antimony and its alloys is that they expand on cooling.
Certain Health Facts About Antimony
- It is toxic but does not have any harmful effects.
- But constant exposure to this may cause some diseases like lung diseases, heart problems and stomach ulcers.
