Abstract

The pressure–volume equations of state of palladium and rhodium statically compressed in neon are presented. Vinet fits give parameters for palladium: V0=58.678(73) Å3, B0=189.3(30) GPa, B0′=5.473(63), and rhodium: V0=55.062(63) Å3, B0=241.3(65) GPa, B0′=5.34(24). Both metals are observed to react with hydrocarbons under pressure to form hydrides. Existing equations of state are discussed with regard to potential inadvertent hydrogen contamination as a source for discrepancies and anomalous fitted parameters.
