5 Uses
5.1 Uses & Benefits
- 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.
- Silver is mainly used for Jewelry and show piece.
- It is used for manufacturing high quality mirrors due to its reflectivity property.
