The Problem Of The Tensleep Sandstone, George D. Mccarthy May 1947

The Problem Of The Tensleep Sandstone, George D. Mccarthy

Bachelors Theses and Reports, 1928 - 1970

Sandstone is probably one of the most important groups of rocks in existence today. The economic importance of so insignifi­cant a thing as a mass of sand grains grows with the true reality of the situation. By increasing our knowledge of grains of sand, or particles of sandstone in all their ram­ifications, it would undoubtedly reflect upon our everyday life by increasing commercial possibilities of an undevel­oped natural resource of Montana.

Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland

Bachelors Theses and Reports, 1928 - 1970

Sometime prior to 1870, a group of prospectors made what was believed to be a "rich strike' on one of the tributaries of Prickly Pear Creek in Jefferson County, Montana. Instead of striking it rich, they had uncovered a native copper deposit, worthless to them because of its limited extent and remote location, but now of much interest to the geologist, and to the mining engineer because of its possible commercial value.

The Use Of Carbides In Refractories, James Adamson Crookston Jan 1947

The Use Of Carbides In Refractories, James Adamson Crookston

Masters Theses

"With the new demands being made on the ceramic industry in mind, it was thought that an investigation of the ceramic possibilities of certain high melting refractory materials might prove of interest and value. The high melting materials are the oxides, carbides, nitrides, borides, and hydrides. Since a great deal of work has been done on the oxides, and relatively little on the others, the oxides were dismissed. Of the other groups, the carbides seemed interesting. Of the carbides, the following materials were chosen for investigation: Boron Carbide (B₄C), Zirconium carbide (ZrC), and Titanium carbide (TiC). These materials were chosen …

The Use Of Wetting Agents In Clay Bodies, Nathan Russell Sewell Jan 1947

The Use Of Wetting Agents In Clay Bodies, Nathan Russell Sewell

Masters Theses

"It has been observed that one of the weak points in the present method of commercially preparing stiff mud bodies is the de-airing process, which involves passing them thru a vacuum chamber. Difficulties in maintaining a good vacuum, power costs, and work stoppages due to clogged vacuum chambers, are some of the problems. It was thought that perhaps a very definite contribution could be made in the field of ceramic engineering if some method could be devised for preparing a workable ceramic body of good dry and fired properties without the use of a vacuum chamber. In attacking the problem, …

Ceramic Possibilities Of Some Missouri Clays And Shales, Leonard Nathanael Larson Jan 1947

Ceramic Possibilities Of Some Missouri Clays And Shales, Leonard Nathanael Larson

Masters Theses

"Although many of the shales and clays of Missouri have in the past been, or are presently being used for the manufacture of heavy clay products such as face brick, common brick, sewer pipe, and tile, there is in these post-war years a significant shortage of these products within the state and country. Especially in the northwestern part of Missouri is there a distinct shortage, as only one structural clay plant is known to be operating in that area. The St. Louis and Southeastern Missouri districts are better prepared to meet construction demands, with several structural clay plants operating at …

Rapid Determination Of Alumina In Diaspore Clays, Matthew Julius Kerper Jan 1947

Rapid Determination Of Alumina In Diaspore Clays, Matthew Julius Kerper

Masters Theses

"The alumina content of the diaspore clay is the index to its refractoriness, so it is important to know the alumina content of the diaspore clay. Diaspore is mined in comparatively small pits and naturally the alumina content will vary from pit to pit and will vary to a considerable extent in the same pit. Since a uniform finished product is desired, the alumina content of each pit must be known and frequent checks run on the output of the pits. Chemical analysis is the standard method of determining the amount of alumina in clays. The main objections to chemical …

Some Preliminary Work On Metaphosphates In Ceramics, John Frederick Burst Jan 1947

Some Preliminary Work On Metaphosphates In Ceramics, John Frederick Burst

Masters Theses

"For a good many years the accepted method of cementing ceramic joints was with a mixture of fire clay grog and a plastic clay binder. This did not prove too satisfactory for several reasons. Usually when enough plastic clay was added to give good workability the vitrification was lowered to such an extent that either excessive shrinkage or excessive bloating occurred, depending upon the extent to which the vitrification point was exceeded...In order to obtain a cement with high strength throughout a long firing range the manufacturers have turned to the addition of various organic binders and inorganic fluxes. Most …

Action Of Diatoms On Clay, Joseph Harvey Renfrew Jan 1946

Action Of Diatoms On Clay, Joseph Harvey Renfrew

Masters Theses

"With the recent trend toward the use of higher temperatures and more severe service conditions in the metallurgical and refractories industries there has developed a constantly greater demand for high-alumina clays, that is, clays in which the alumina content is considerably above that of pure kaolinite, Alâ‚‚O₃2SiO₂·Hâ‚‚O. However, the known reserves of good diaspors are so small that ceramic engineers are already turning to basic refractories in order to have sufficient materials for work at high temperatures. Even the slightest reflection on the needs of the refractories industry will show that such substitutions are strictly limited, and possible only where …

Ceramic Properties Of The Clays Of The Polo Gas Field, Clarence Arthur Lambelet Jan 1946

Ceramic Properties Of The Clays Of The Polo Gas Field, Clarence Arthur Lambelet

Masters Theses

"In Western and Northwestern Missouri there exist many natural gas fields of such limited size and of such great dispersion that it is not economical to utilize their products by the construction of pipe lines to consuming centers. Thus a large source of natural wealth is lying idle. This wealth could be utilized, however, if some manufacturing process requiring large amounts of fuel were located in the vicinity...The availability of fuel is the reason for interest in the area, though an investigation should be made to assure the quality and quantity of the fuel in any selected area. the adequacy …
