Evaluation Of Commercial Titanium Alloys, Robert Loucks
Evaluation Of Commercial Titanium Alloys, Robert Loucks
Bachelors Theses and Reports, 1928 - 1970
Uses of titanium and its alloys range from aircraft structures to corrosion-resistance applications. The properties of the metal, including physical metallurgy, naturally dictate the folds of application. The interstitial elements, plus aluminum and tin, preferentially stabilize the alpha phase of titanium.
The Design And Construction Of A Laboratory Model Fluidized Bed Reactor, Godfrey Paul Howard
The Design And Construction Of A Laboratory Model Fluidized Bed Reactor, Godfrey Paul Howard
Bachelors Theses and Reports, 1928 - 1970
Fluidization has become a new and important unit operation in roasting, calcining, and drying ores because of the economy and ease of handling that it affords. Because of these reasons, and since the Montana School of Mines Metallurgical Laboratory does not have an operating model of a fluidized bed reactor, it was decided to design and construct an operating model for future research in the laboratory.
The Effect Of Strontium Sulfate Addition On The Lead Content Of Electrolytic Zinc, Arthur E. Morris
The Effect Of Strontium Sulfate Addition On The Lead Content Of Electrolytic Zinc, Arthur E. Morris
Bachelors Theses and Reports, 1928 - 1970
The production of electrolytic zinc involves the passage of an electric current through an aqueous solution of zinc sulfate and sulfuric acid. While all plants use procedures fundamentally the same, there are principal differences in the acidity of electrolyte, the zinc content of the electrolyte and the current density used.
Streaming Potential Studies, Andrew L. Mular
Streaming Potential Studies, Andrew L. Mular
Bachelors Theses and Reports, 1928 - 1970
The application of streaming potential to mineral-dressing is comparatively recent. Although colloidal chemists, for some time, have been familiar with streaming potential and the electrical double layer, A.M. Gaudin, Richards Professor of mineral-dressing, M.I.T, and D.W. Fuerstenau, his assistant, were the first to publish a series of experiments dealing directly with streaming potential applied to flotation. The apparatus described in this thesis was used by Fuerstenau and was developed by him especially for this type of investigation.
Synthetic Manganese Dioxide Production, Russell Marion Dugdale
Synthetic Manganese Dioxide Production, Russell Marion Dugdale
Bachelors Theses and Reports, 1928 - 1970
Before World War I the United States procured all of its battery grade manganese dioxide from the Caucasus. Even at this time some experimentation was under way to produce this depolarizing substance synthetically and the experiments were successful to a large extent so that when the ore from the Caucasus was cut off, the necessary material was produced synthetically. The shortage was relieved when a deposit of manganese dioxide was discovered in Montana, which was superior to the ore from the Caucasus.
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
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.
