“…However, the partial pressures calculated for these measurements were much higher than expected on the basis of earlier work (1,5) : by factors of about ten in one set of experiments and of about four in the other. This was evidenced by reproducible rates of mass loss at a given temperature with intervening measurements at other temperatures.…”

“…Ithas been observed, during the preparation of manganese phosphide samples fo.r study by x-ray photoelectron spectroscopy (7), that MnsP(s) loses manganese in vacuum at high temperature to give Mn2P(s). Hence the Mn2P solid single phase region must include a congruently vaporizing composition since MnP(s) loses phosphorus to give Mn2P(s) (1). The enthalpy change for the congruent vaporization reaction (under the presumption that the composition is stoichiometric)…”

“…it has been pointed out that the atomization enthalpies per gram atom of the nickel phosphides are, at corresponding compositions, very nearly the same as those for the phosphides of iron, 15 and cobalt,4 but, when valence state energies 1 6 of the metal atom are taken into account, 14 …”

The equilibrium vaporization reactions 12Ni2Pfalse(normalsfalse)=2Ni12P5false(normalsfalse)+P2false(normalgfalse) and 6.8Ni12P5false(normalsfalse)=32Ni2.55Pfalse(normalsfalse)+P2false(normalgfalse) have been studied by mass‐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), normalΔHnormalf0/R , and enthalpies of atomization, normalΔHnormalat0/R , respectively, in kilokelvins at 298.15K:1/4 Ni3Pfalse(normalsfalse),−5.94±0.5,54.8;1/3.55 Ni2.55Pfalse(normalsfalse),−6.65±0.5,55.2;1/17 Ni12P5false(normalsfalse),−6.73±0.5,55.1;1/3 Ni2Pfalse(normalsfalse),−6.87±0.5,54.8;1/9 Ni5P4false(normalsfalse),−6.39±0.5,53.0;1/2.22 Ni1.22Pfalse(normalsfalse),−6.32±0.5,52.9;1/2 normalNiPfalse(normalsfalse),−6.09±0.5,52.1;1/3 NiP2false(normalsfalse),−5.38±0.5,49.4;1/4 NiP3false(normalsfalse),−4.52±0.5,47.6 .
