Applications:

Yttrium is transition metallic element with chemical properties similar to the lanthanide elements. It is not found free in nature it is found
with other lanthanides elements. It is highly crystalline and is moderately stable in air. Yttrium has the highest thermodynamic affinity for
oxygen of any element. It has the ability to form crystals with useful properties.

Yttrium has many applications due to its properties. It is used in alloys to reduce the grain size and increase the strength of the metals.
It also improves the workability, adds resistance to high-temperature recrystallization and enhances resistance to high temperature oxidation.
Yttrium has applications in electronics. It is used in making liquid crystal display panels and in fluorescent lightning. It is used in the development
of superconductors, ceramics, and special glasses. Yttrium has also applications in medicine. It is used in manufacturing of artificial joints and other
prosthetic devices. Its radioactive isotopes are used in the treatment of cancer lymphoma and leukemia.
