The heat of hydride formation for the alloys decreased with increasing Pt or Ni content. The isotope effect defined as the equilibrium pressure ratio, PD2/PH2, did not change much with alloy composition. The equilibrium constant at infinite dilution showed strong temperature and isotope dependence. Analysis indicated the ground state of D to be 1/√2 less than that of H for respective alloys. The thermodynamic properties of hydride phase were evaluated for all the alloys and hydrogen isotopes including tritium., Article}, pages = {81--94}, title = {Pd-Pt及びPd-Ni合金中における水素同位体の熱力学特性}, volume = {18}, year = {1998} }
