Dysprosium Hydride(DyH2~3)-Powder
Characteristic
Dysprosium hydride is a compound of hydrogen and dysprosium. 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 permanent magnets field. Dysprosium is a chemical element with the symbol Dy and atomic number 66. It is a rare earth element with a metallic silver luster. As-cast dark gray powder is extremely susceptible to oxidation and ignition in the air.
