摘要：

A relatively pure MS2Ni intermetallic compound was prepared by partial melting and sintering. Absorption and desorption pressure-composition isotherms for the Mg2Ni-H-2 system were obtained. The relationships between the equilibrium plateau pressure (P-eq) and the temperature were log P\ = - 3,211/T + 6.2220 for absorption, and log P\ = - 3,300/T + 6.2612 for desorption. The procedure to obtain the pressure-composition isotherms was explained and a method to calculate the composition for pressure-composition isotherms ("the summation method") was also suggested.
