Uses
Uses & Benefits
- Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
- Its oxide is used as pigments for glass and ceramics.
- Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
- It is also used as a catalyst in ethene polymerisation.
