Outline of Final Research Achievements |
The new hydrides of lithium hydride and beryllium were synthesized by applying high pressure and high temperature onto the mixtures of lithium and hydrogen, and beryllium and hydrogen. The synthesized lithium hydride was found to contain H2 molecule in its crystal lattice, and it was an insulator up to 180 GPa. The synthesized beryllium hydride was found to posses the crystal structure that is different from already known BeH2. The synthesized BeHx did not show apparent transition to metallic state up to 40 GPa. The synthesis of H2-containg metal hydride has not been reported so far. This study opens up the new filed of study about the new metal hydrides that contain H2 molecules in is crystals.
