A Study of Eutectics of Certain Fused Salts

Considerable work has been done investigating the freezing point curves of fused salts, but little has been written describing the appearance of their eutectic structures when observed under the microscope.

The Electroformation of Lithium-Lead Alloys from Molten Electrolytes

An attempt was made to make lead-lithium alloys by electrodeposition of lithium using a molten bath and a molten lead cathode.The variables taken into consideration were: composition of the melt, temperature of the melt, and current density. The purpose of changing these factors was to determine what effect each had on the current efficiency.

The Extraction of Chromate Salts from Montana Chromite

In this thesis I have tried to determine the suit­able temperature, time and the amount of soda ash and lime needed for the calcining process. The leaching and purification tests were studied experimentally. The earlier process for making chromate from chromite was not the same as is used today. There­fore I have found it useful to put into this thesis the newest method for making chromate salts and their important uses.
