Hydrogen-induced disproportionation of the intermetallic compound ZrCo

Disproportionation of the intermetallic compound ZrCo in the presence of hydrogen into ZrH sub 2 and ZrCo sub 2 has been observed in the temperature range 350-500 deg C during both the absorption and the desorption mode. Quantitative reproportionation into ZrCo can be achieved by vacuum annealing at...

Zusammenfassung:	Disproportionation of the intermetallic compound ZrCo in the presence of hydrogen into ZrH sub 2 and ZrCo sub 2 has been observed in the temperature range 350-500 deg C during both the absorption and the desorption mode. Quantitative reproportionation into ZrCo can be achieved by vacuum annealing at high temperatures. The resistance of a sample toward degradation was found to be determined by its previous history.
