Papers Inst. Phys. Chem. Research (Tokyo), vol. 23, 1933, pp. 164-172.  Chem. Abs., vol. 28, 1934, p. 2589.

       Reduced Ni was successfully heat treated in H₂ for 1 hr. at temperatures ranging 300°-500°.  Between each heat treatment the adsorptive capacity for H₂ at 0° and 20.3 cm. pressure was measured.  Increasing temperatures of heat treatment shortened the time necessary for adsorption to reach equilibrium and diminished the quantity of H₂ absorbed.  The velocity with which A diffused into reduced Ni was unaffected by heat treatment up to 500°.
