The Gallium-Indium Constitutional Diagram, Richard E. Gaffney

Bachelors Theses and Reports, 1928 - 1970

Because of the discrepancy as to whether there is solid solubility in the gallium-indium system, and the fact that no alloys with less than 1% indium were ever investigated; the possibility of solid solubility in either or both ends of the diagram was not overlooked. According to Hume-Rothery, two alloys with the same relative positions on the Periodic Chart should have about the same alloying habits.

Electrowinning With Amalgam Electrode, Ralph V. Anderson Jr.

Bachelors Theses and Reports, 1928 - 1970

Amalgam Metallurgy, a relatively new expression in the technology of metal extraction, was first chosen to describe certain new processes developed at the Duisburg Copper Works in Germany. The idea of using mercury, a costly and poisonous metal, as an intermediate in heavy chemical industry and in polarography are of recent origin; with the exception of a series of patents of little signif­icance and occasional comments in the literature, the work is hardly known.

Electro-Galvanizing From A Purified Ammonium Sulphate Leach Of Anaconda Zinc Calcine, Phillip J. Mischkot Jr.

Bachelors Theses and Reports, 1928 - 1970

Ever since the introduction of metal products into our civilization, especially those of iron and steel, man has been confronted with the problems of corrosion prevention. As the agents which are conducive to cor­rosion cannot be completely eliminated, it has been necessary for man to develop processes and materials that will retard the degeneration of the metals that are so important to our industrialized world.

Resistance Of Solid Inconel To Attack By Liquid Indium, David C. Hendra

Bachelors Theses and Reports, 1928 - 1970

The role of liquid metals in industry is rap­idly becoming of increasing importance. The phys­ical and chemical tendencies of metals in the liq­uid condition must be ascertained before a metal in this form can be put to practical usage. In very many stages of mineral processing and recovery, in molten-metal baths for temperature control on heat treating, and in several industries where heat transfer is an important aspect, metals may be at one time or another in a liquid condition.

A Microscopic Study Of The Ore Minerals From The Mines In The Northern Part Of The Zosell (Emery) Mining District, John P. Joyce

Bachelors Theses and Reports, 1928 - 1970

Any investigation of the many gold silver producing districts of Montana will necessarily include the name Zosell. The Zosell Mining District, often referred to as the Emery District, was never a major producer in the state; however, its location, history, type of deposit, and char­acter of ore, has drawn the interest of many prominent investigators of the mineral industry.

Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta

Bachelors Theses and Reports, 1928 - 1970

The exact upper boundary of the Devonian of Mont­ana has long been a controversy, as is true of the Dev­onian-Mississippian contact in many other localities. In an effort to delimit the upper Devonian, various paleontologic studies have been made, more especially in the southwestern part of the state.

Geology Of A Postulated Volcanic Vent Northeast Of Whitehall, Montana, C. H. Hewitt, H. D. Olson

Bachelors Theses and Reports, 1928 - 1970

The possibility of defining the roots of one of the volcanic sources of the Upper Cretaceous Livingston formation led to the detailed mapping upon an enlarged aerial photograph of a complexly intruded, folded, and faulted area about 10 miles northeast of Whitehall, Montana.

A Listing Of Montana Invertebrate Fossils And A Bibliography Of Montana Paleontology, Robert G. Ingersoll

Bachelors Theses and Reports, 1928 - 1970

The oldest system in which identifiable invertebrate fossils have been found is the Cambrian. The basal Cambrian formation found in Montana is the Flathead sandstone and quartzite of Middle Cambrian age. No fossils have been reported from this formation. Above the Flathead is the Wolsey formation composed of green fissile shale with sandy and limy members. This fossiliferous member of the Middle Cambrian is known in Northwestern Montana as Gordon, and in the Philipsburg quadrangle as the Silver Hill formation.

Mineralogy Of The Silver King Mine Of Park City, Utah, Pierce D. Parker

The mines at San Jose which are within the Wadley unit are the largest antimony mines in Mexico. These mines produce more than half of the antimony produced by the company from its mining operations. Since the time of the author's connection with the company, a number of changes have been made in planning of development work, handling of labor, methods of mine development, cost improvement, and other problems inherent in the successful guidance of an operation.

A Study Of Some Raw Materials For The Manufacture Of Silica Brick, Charles E. Shulze

Masters Theses

"The ability of silica to carry a load to within a few degrees of its melting point and its tolerance for comparatively high concentrations of iron oxide and lime, have enabled it to maintain its position as the number one steelplant refractory. It is estimated that at least half of the volume of refractories used in the steel plant are silica bricks. Consequently the manufacture of silica refractories forms an industry of considerable importance.

Raw materials suitable for the manufacture of silica brick are widely distributed, but only a small number of deposits are used commercially for one reason or …

An Investigation Of Ruthenium As A Possible Ceramic Colorant, John Charles Williams

Masters Theses

"Some portion of almost every writing dealing with the historical development of ceramic products is devoted to describing the application of colors as found on even the most ancient specimens known to exist. A vase bearing the name of an Egyptian king living 5000 B. C. was glazed in green and inlaid with purple. There are many such examples of the utilization of color in ceramics which illustrate to a certain extent the aesthetic tastes of the very earliest and primitive civilizations.

In those early times, only a few elements were known and available that could be used for such …

Bauxite Versus Diaspore Clay In High Alumina (70%) Refractory Brick, Bhikhubhai Mahadeo Sedalia

Masters Theses

"The last twenty five years have seen a remarkable change in the character and types of refractories for furnace construction. Not much more than a few years ago, the production of refractories consisted almost solely of fireclay and silica shapes. A few high alumina bricks were made from Missouri diaspore clays or from bauxite and fire clays. At a later date, although little used, high alumina refractories were available which were made from alumina of a higher degree of purity, by the fusion process. Today refractories covering the entire range of composition from about 98% SiO₂ to 99 1/2% …

Czarina Mine, Butte, Montana, Prodyot K. Das

Bachelors Theses and Reports, 1928 - 1970

The Czarina mine operated for a short time during the last Great War, lies in the southwestern corner of the Butte mining district of Montana. This area was worked during the extensive silver mining in Butte during the 1890's, and was prospected from time to time in later years. The orebody of the mine consists of fissure fillings of manganese mineral oxidized to a certain depth, in a fracture zone of the Boulder Batholith.
