Antimony: The Element of Stability
Antimony is a silvery-white metalloid that is highly stable and an important element in our day-to-day life. This element has extensive uses in industry, especially in making lead-acid batteries, unique alloys, and flame-resistant products.
The term ‘Antimony’ comes from Greek which meant “unstable”.
History and Discovery of Antimony
Antimony is thought to have been discovered by the Ancient Chinese around the 3rd to 5th century BC. The Chinese referred to it as ‘k’ang’ in their books.
It is believed that the first person to isolate antimony was a Swiss scientist called Valentin Rose in 1720. He called it ‘Stibium’. Antimony is found naturally in the Earth’s crust mainly as an ore – stibnite.

Uses of Antimony
| Uses in | Description |
|---|---|
| Alloys | Antimony is used to make alloys like pewter, type metal, and babbitt metal, which find applications in phone cases, bearings, musket balls, and lead bullets. |
| Fire Retardants | Antimony trioxide is used in various plastic appliances as a fire retardant, helping to inhibit the combustion process and enhance fire safety. |
| Batteries | Antimony is used as an alloy in making lead-acid batteries, supporting energy storage and providing power in various applications. |
| Glassmaking | Antimony is used in glassmaking to refine the optical and thermal properties of glass, making it suitable for a range of applications. |
Safety Precautions
Antimony can be harmful if inhaled or ingested. When working with antimony it is advised to wear protective clothing, goggles and gloves. One should also take caution in avoiding contact with skin and eyes.
Antimony should be stored in tightly sealed containers away from food and water. It is also suggestible to consult with a professional regarding the usage and disposal of antimony.
Conclusion
Antimony is an amazingly stable element with many important uses that make our life easier. It is beneficial in creating alloys, as a fire retardant, and making lead-acid batteries. It was first discovered by the Chinese centuries ago and is still used in many industries to this day. Yet, it is important to take necessary precautions when using antimony and to store it in tightly sealed containers.
Overall, antimony makes it possible for us to enjoy the advanced technologies of today.
