Reaction of Hydrogen with Uranium

Abstract

The reaction of hydrogen with uranium to produce uranium hydride was studied in the temperature range 96°–400°C at pressure levels of of mercury (where is system pressure and is the plateau dissociation pressure of the uranium hydride product). Reaction rates followed the linear law. At a given , the linear rate increased with increasing temperature in the range 96° to about 250°C and decreased with increasing temperature from about 250° to 400°C. Variation of the linear rate with temperature and pressure in the range 96° to about 250°C is given by the equation:
