Vaporization Behavior of Chromium Phosphides. The Solid Two-Phase Regions CrP-Cr12P7, Cr12P7-Cr3P, and Cr3P-Cr.

Abstract

The vaporization reactions 24/5 CrP(s) = 2/5 Cr12P7(s) + P2(g) (1194-1479K), 2/3 Cr12P7(s) = 8/3 Cr3P(s) + P2(g) (1421-1541K), and 2 Cr3P(s) = 6Cr4(S) + P2(g) (1543-1768K) have been studied by mass-loss effusion in the temperature ranges indicated. The reactions are kinetically inhibited. Enthalpies of formation and atomization respectively were found. Cr P was found to follow the trend in atomization enthalpy to valence state atoms established in the series MnP, FeP, CoP, and NiP.
