Abstract
The reduction of a uranium oxide (U3O8) and nickelous oxide (NiO) by hydrogen atmospheres has been studied using a Cahn RG electrobalance. The oxide samples were prepared by the thermal decomposition of selected nickel and urariyl salts. Heating of the product oxides caused sintering observable as a decrease in surface area. The effect of this sintering on the rates of reduction of the oxides has been investigated in a series of isothermal experiments. The kinetics of the reduction process are investigated and possible reaction mechanisms are suggested.
