Abstract
The kinetic features and mechanism of reduction of gamma-Fe2O3 in hydr ogen in the presence of CaO as a getter for the gaseous reaction produ cts was studied. Data were obtained on the kinetic constants, reaction rate, and evolution of surface area during the reaction. It was estab lished that the getter has a favorable effect on the degree of dispers ion of the reaction products.
