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.
- Uses of Scandium are limited to research purpose only. However, it has very low density and higher melting point.
-
Its compounds like scandium iodide is used in mercury vapor lamps to produce very bright white light.
