The Vapor Pressure of Liquid Bismuth Between 603 and 638°C

Abstract

The vapor pressure of liquid bismuth in the temperature range 603-638°C has been measured by the method of molecular effusion. The weights of the metallic deposits were weighed directly with a microbalance. The seven experimental values reported are fairly well represented by the empirical equation: ${log}_{10}p \left(\mathrm{in}\mathrm{mm}\right)=\frac{-52.23\mathrm{}\left(205\right)\mathrm{}}{T}+9.03\mathrm{}$. This expression is in very good agreement with that given in the International Critical Tables.
