The determination of the vapour tensions mercury, cadmium and zinc by a modified manometric method

This research, conducted in the Metallurgical Department of the National Physical Laboratory, arose out of investigations on alloys of cadmium and of zinc, and had as its object the development of a method for determining the vapour pressure of such alloys. In this method the substance under examination is used as the liquid in the manometer, which is employed to indicate a balance between the vapour tension of the substance with an externally applied pressure of nitrogen.
