The process of NiO structure reconstruction under reduction treatment by a CO/H[sub 2] mixture has been studied using in situ X-ray powder diffraction and transmission electron microscopy. It was found that there are two different forms of phase transformation (NiO [yields] Ni[sub 3]C and NiO [yields] Ni) depending on the microstructure of the initial NiO specimen.
