Cerium Hydride(CeH2~3)-Powder
Characteristic
Cerium metal (γ-phase) at room temperature possesses the face-centered cubic (fcc) structure. Upon incorporation of hydrogen and beyond its solubility limit, CeH2 is first formed as the hydride H− ions occupy the tetrahedral sites in the fluorite fcc structure. Increasing hydrogen stoichiometry leads to a series of well-defined H-stoichiometry and temperature dependent structures. As the additional H− ions occupy the octahedral sites, the highest stoichiometry of CeH3 is achieved, possessing a BiF3-type structure.
