The equilibrium pressure of hydrogen gas above solid face centered cubic (fcc) phase of chromium hydride has been determined at 150°C. As compared to the hexagonal close packed (hcp), chromium hydride plateau for the a+β phase region has been found to be lower by about 500 bars and equal to 0. 25 ± 0. 01 GPa. The search for possible pressure induced phase transition from the fcc to the hcp structure has been unsuccessful up to 37 GPa. The compressibility of the fcc hydride is similar to that of the hcp phase, showing pressure independence of the hydrogen volume in the metal lattice, and confirming the general rule observed in transition metal hydrides.
