Vapor Pressures & Relative Stabilities Of Certain Double Flourides, Walter L. Gage

Missouri School of Mines and Metallurgy Reports

The vapor pressures and relative stabilities of certain double fluorides such as sodium titanium fluoride and strontium titanium fluoride will be investigated by heating them under vacuum to determine the extent of evaporation or decomposition.

Direct Reduction Of Zinc Sulfide Under Vacuum -- Course Work, Merritt E. Langston

Missouri School of Mines and Metallurgy Reports

A study of the reduction of zinc sulfide under vacuum by such reducing agents as iron, calcium oxide and carbon, graphite, and iron and carbon.

An attempt to refine the impure zinc metal condensates obtained from the above reductions under under by the mechanism of a differential displacement of the volatile constituents.

Progress Report: Reduction Of Zinc Sulfide, Merritt E. Langston

Missouri School of Mines and Metallurgy Reports

To date the work which has been completed has been concerned with an attempt to duplicate the results reported by Liu in his thesis. In short, little can be said in comparing the two separate investigations because there does not seem to be any apparent similarity, even though the operating conditions were kept as nearly the same as possible. Figure 1 shows the lack of agreement for the amount of total zinc distilled, expressed as weight percent....

A Report On The Reduction Of Sphalerite Under Reduced Pressure, John H. Fuqua, William H. Magruder

Missouri School of Mines and Metallurgy Reports

During the last war, with the increased demand for magnesium metal and the general disregard for costs, a number of plants were constructed for the production of magnesium by vacuum metallurgical methods. (Both the Carbothermic Process and the Pidgeon Ferrosilicon Process employ vacuum systems for the production of metallic Mg.)

At the close of the war several of the government built plants were forced to suspend operations because of the economic impossibility of producing magnesium in competition with the Dow Chemical Company. It was with the availability of these plants in mind that experimentation with the possibilities of producing metallic …
