Kinetics and mechanism of hydrogen-induced disproportionation of ZrCo

摘要

The kinetics and mechnism of the hydrogen-induced disproportionation of ZrCo was studied experimentally. In general, the time dependence of the disproportionation has a sigmoidal shape. The disproportionation rate increased with increasing initial hydrogen pressure and showed a 3/2-power dependence on the pressure. As for the temperature dependence, the rate increased with temperature only up to 815 K and then decreased at higher temperatures.
