7 Uses
7.1 Uses & Benefits
- Currently known uses of Copernicium metal are limited to research purpose only.
- It has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
- Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.
