Freezing Pressure of Mercury Using Improved Apparatus and Technique

A Redetermination of the Freezing Pressure of Mercury

A number of improvements in apparatus and technique have been made since the production of the prototype model of the controlled-clearance piston gage used by Johnson and Newhall in their 1953 determination of the freezing pressure of mercury at 0oC.

 

These improvements and the importance of this value have justified the redetermination report herein.
