摘要
The reaction of hydrogen with uranium powder was investigated at 13.3 and 26.6 kPa between 50° and 250 °C. The reaction order was independent of temperature but varied from two-thirds order at 13.3 kPa to first order at 26.6 kPa. Increasing temperatures resulted in decreasing reaction rates over the temperature range studied. A reaction mechanism with adsorption as the ratecontrolling step is proposed to explain the temperature behavior. Decomposition of the hydride was found to follow a zero-order rate process. © 1979, The Electrochemical Society, Inc. All rights reserved.
