Compressibility study during hydride reaction of ZrCo

The compressibility effect on the hydride reaction of ZrCo, intermetallic compound, was studied using a visual cell reactor. In this study the compressibility effect on the hydride reaction of the ZrCo getter material was investigated by measuring the hydriding rate and monitoring the behavior through a visual cell. As a result, the ZrCo hydride reaction is found that the compressibility to the hydride reaction state has an effect on the initial hydride reaction rate and the final saturation state. For the hydride reaction of the ZrCo under pressurized reaction the log t1/2 vs. log(p/p0) is well represented by a straight line as the overall irreversible reaction having nth order reaction, where n is nearly 0.1. Even though the hydride reaction rate of the ZrCo is strongly hindered by the system compressibility, the inclination of hydride formation and the volume expansion could be propagated in a limited container space.
