Abstract
The effect of graphite and BN on hydrogen absorption by Ti under milling in H2/He flow and on the thermal stability of Ti-hydride produced during milling is compared. BN is the more effective additive than graphite to improve hydrogen sorption capacity of Ti because of the stimulation of a higher hydrogen uptake. Both additives stimulate the formation of occupation sites characterized by a H2 desorption temperature that is up to 400 K lower than that of pure Ti. The reasons for the higher performance of hexagonal BN as compared to graphite are found to be entropic in nature.
