4 Uses
4.1 Uses & Benefits
- The most common use of cesium metal is as a drilling fluid. It is also used in optical glass manufacturing.
-
In vacuum tubes and radiation monitor equipment this metal is used as a catalyst promoter.
- Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
-
Thi metals alloy is used in magnate as it is resistance to high temperature.
