ABSTRACT:
The present invention relates to a method and apparatus for preparing metal-embedded porous metallic-hydride (pmh) compacts capable of with standing repeated hydriding-dehydriding cycles without disintegrating. According to the invention, the finely divided hydridable metal alloy hydride is admixed with a finely divided metal selected from Al, Ni, Cu or other transition metals and charged with hydrogen. The resulting mixture is sintered in a furnace in which hydrogen is introduced at a pressure above the equilibrium pressure to the prevailing temperature, mechanical stress being applied simultaneously. The compacts obtained possess outstanding stability, as shown by the fact that they have remained intact even after more than 6000 cycles.
