Thermodynamics of the Vaporization of Nickel Oxide

Abstract

A mass spectrometric investigation of the vapor species in equilibrium with nickel oxide has shown the vapor phase to consist of Ni, O2, NiO, and O, whereas the solid phase consists of a NiO solid solution and Ni(s). The dissociation energy of NiO(g) was found to be 86.5±5 kcal/mole.
