3 Uses
3.1 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.
- It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
