Abstract
Vapour pressure equations are presented for the metallic elements up to curium. For each element a precise four-term equation and a more practically-based equation have been derived from a new evaluation of thermochemical data for the condensed and gaseous elements. It is intended that the equations should be used for ideal gases in the pressure range 10−15–10−3 atm, which covers the experimentally accessible range. The “precise” equations reproduce the data to better than ±1% and the “practical” equations provide better than ±5% accuracy.
