Vaporization Behavior, Phase Equilibria, and Thermodynamic Stabilities of Nickel Phosphides.
Abstract
The equilibrium vaporization reactions, 12 Ni2P(s) = 2 Ni12P5(s) loss effusion in the temperature range 1237-1401 K. The results were combined with published calorimetric data for nickel-rich samples and static phosphorus dissociation pressure data for phosphorus-rich samples, with consideration of the requirements of the published phase diagram, to obtain enthalpies of formation (from red P), Delta H sub f deg, and enthalpies of atomization, Delta H deg at/R, respectively, in kilokelvins at 298.15 K: 1/4 Ni3P(s), -5.94 + or - 0.5, 54.8; 1/3.55 Ni2.55P(s), -6.65 + or - 0.5, 55.2; 1/17 Ni12P5(s), -6.73 + or - 0.5, 55.1; 1/3 Ni2P(s), -6.87 + or - 0.5, 54.8; 1/9 Ni5P4(s); -6.39 + or - 0.5, 53.0; 1/2.22 Ni1.22P(s). -6.32 + or - 0.5, 52.9; 1/2 NiP(s), -6.09 + or - 0.5, 52.1; 1/3 NiP2(s), -5.38 + or - 0.5, 49.4; 1/4 NiP3(s), -4.52 + or - 0.5, 47.6.
