Silane (SiH 4) is found to (partially) decompose at pressures above 50 GPa at room temperature into pure Si and H 2. The released hydrogen reacts with surrounding metals in the diamond anvil cell to form metal hydrides. A formation of rhenium hydride is observed after the decomposition of silane and...
