Abstract

Experiments are reported on the rate of reduction of nickel oxide pellets with hydrogen over the temperature range 200° to 900°C. Measurements were also made of the pore size distribution of the reacted and unreacted specimens, by mercury porosimetry. In addition, the size of the individual grains was also determined by X-ray diffraction techniques and by electron microscopy. These physical measurements supplied most of the information required for the comparison of reduction rates with the predictions made in Part I of this study. It was found that the trends predicted by the structural model were consistent with measurements, thus the, structural model shows promise both for the interpretation of experimental data and for the semiquantitative prediction of experimental behavior.
