Applications
Yttrium is an additive in one of the coolest types of superconductors out there: the yttrium barium copper oxide superconductor. What is special about this superconductor is that it is able to operate above the boiling point of liquid nitrogen, a much cheaper alternative to the normal superconductor coolant, liquid helium.

Yttrium is being experimented with in the production of higher energy dense lithium ion batteries, the battery of the future. Instability is a recurring issue at the moment.

A synthetic crystal called the yttrium aluminum garnet is used in lasers that cut through metal. Pretty cool.

Yttrium oxide is an additive used in glass for camera lenses to make them stronger and more impact resistant.

A commonly used catalyst in polymers and alloying agent in aluminum and magnesium based metals, Yttrium has a wide range of very cool applications.
