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, B'₀ = 5.473(63)⁠, and rhodium: V₀ = 55.062(63) Å³⁠, B₀ = 241.3(65) GPa, B'₀ = 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.
