The vapor pressure of palladium was studied using a Knudsen effusion cell and a commercial thermogravimetric balance. Vapor pressures were measured using four Knudsen cells of different effusion areas with consistent results. Most of the available vapor pressure data for palladium has been taken below the fusion temperature, and only a few experimental studies exist on the vapor pressure of liquid palladium. In this current study, vapor pressures were measured from 1473 K to 1973 K ( from well above and well below the melting point). In addition, the range in temperature covered in the current study represents one of the largest continuous investigations of palladium vapor pressure to date. The standard enthalpy of sublimation calculated via a third-law analysis of the vapor pressure data is (377.7 +/- 0.2) kJ (.) mol(-1), in excellent agreement with the recommended value of (377 +/- 5) kJ (.) mol(-1) from the most recent review of available palladium vapor pressure data.
