5 Uses
5.1 Uses & Benefits
- Currently known uses of Flerovium metal are limited to research purpose only.
- Thallium is a toxic metal and hence it has limited uses. Thallium metal is mostly used for producing photoelectric cells.
- In thermometer’s mercury alloy has 8% of thallium, as it has a melting point lower than 20°C.
