Yttrium Hydride(YH2~3)-Powder
Characteristic
Yttrium hydride is a compound of hydrogen and yttrium. It is considered to be a part of the class of rare-earth metal hydrides. Metal hydrides are very attractive and important materials in the nuclear energy field. In particular the yttrium hydride is significantly stable at high temperature, therefore it is expected to be used as material for weakening neutron energy spectrum of the fast reactor. However, various properties of yttrium hydride are hardly known and there are very few reports about them. This is attributed to the fact that metal hydrides are cracked or pulverized in a usual fabrication process.

Application
When containing a substantial amount of oxygen, yttrium hydride is also found to exhibit reversible photochromic properties. This switchable optical property enables their utilization in many technological applications, such as sensors, goggles, and medical devices in addition to the smart windows. According to a research results, the strength of the photochromic response is found to decrease with increasing oxygen concentration in the film accompanied by an optical band gap widening.
Yttrium hydride is being looked at as a high temperature superconductor.
Yttrium hydride is being looked at as a neutron moderator for use in new nuclear reactor designs.
Package
