Production Of Iron, Chromium And Nickel By Amalgam Metallurgy, Richard Earl Westerman
Production Of Iron, Chromium And Nickel By Amalgam Metallurgy, Richard Earl Westerman
Bachelors Theses and Reports, 1928 - 1970
Certain properties of mercury, such as its affinity for other metals, its high hydrogen overpotential, and its unique liquid state, have made its use desirable for many applications in the fields of physical and process metallurgy. Though considerable research has been done on mercury amalgams, only comparatively recently has it been shown that mercury amalgams follow certain definite laws with regard to phase exchange phenomena and electrochemical properties. It is now possible to predict, with considerable accuracy, the results of amalgam reactions.

The Zone-Refining Of A Lead-Bismuth Alloy, Edward James Westerman
Bachelors Theses and Reports, 1928 - 1970
Zone-refining, the purification of a metallic ingot resulting from the passing over its length of a comparatively short molten zone, has been found useful in the purification of several metallic elements. The impurities present in an elemental metal are often more soluble in the molten zone than in the solid material, and are carried to one end of the bar in the molten zone. This molten-zone movement can be repeated any number of times on a metallic ingot, with the zone always being moved in the same direction.
