Facts about antimony
Here are a few interesting facts about antimony element.
- Antimony was given its name from the two Greek words “anti” and “monos” (which means a metal that is not found alone).
- Around 80% of the world’s antimony production comes from China.
- Earth’s crust contains around 0.2 to 0.5 ppm of antimony.
- Stibnite is a mineral of antimony from which most of the antimony is found.
Properties of antimony
Here is a list of some physical properties and chemical properties of antimony.
