Uses & Benefits
- 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.
- Lutetium metal is used outside research. It has commercial uses like Industrial catalyst for cracking oil refineries of hydrocarbons .
