説明
The following reactions have been studied at 1823 K in CO-CO2 mixtures: reactions between liquid Ni-Co-O or Ni-Fe-O alloys and Al2O3 to form spinel-type double oxides as reaction layers, and reactions between liquid Ni-Co-O or Ni-Fe-O alloys and MgO to form continuous diffusion layers in the solid oxides. The kinetics for the formation of aluminate spinels obeyed the parabolic rate law. The rate of formation of NiAl2O4 in the reaction between liquid Ni-O alloy and Al2O3 was in agreement with the reported values obtained in the solid-state reaction between NiO and Al2O3. The concentration of metal ions was regulated at the MgO surface in contact with the liquid alloys by the oxygen partial pressure, and the flux of metal ions which diffused into the MgO was increased with increasing oxygen partial pressure. Comparison of the results from this study with previous researches into solid-state reactions between oxides suggests that the counterdiffusion of cations through a reaction layer is rate controlling.
