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.
