Metals vapor pressure
This table gives coefficients in an equation for the vapor pressure of metallic elements in both the solid and liquid states. The vapor pressure in the range of 10-15 to 10-3-atmare covered.
The equation reproduces the observed vapor pressures to an accuracy of ± 5 % or better.
