The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson

Bachelors Theses and Reports, 1928 - 1970

Rhenium properties offer many interesting possibilities, therefore any ores containing rhenium would be of considerable value. Its close relationship to manganese in the periodic table led to the belief that manganese ores would be an excellent place to search for the metal. Investigation of the literature of rhenium revealed that no ore was known to contain more than 0.001 per cent of rhenium.

The Development Of A New Process For The Manufacture Of Insulating Refractories, Miles E. Tyrrell

Bachelors Theses

"In as much as the grinding of insulating brick to size after the firing operation is one of the most important and at the same time one of the most expensive operations involved in their manufacture, it was felt that the development of a method for manufacture of insulating brick which would do away with the necessity of grinding after firing would be a very worth while project. With this object in mind it was decided that the logical method would be to incorporate the pore structure in the mix while green and at the same time to add some …

A Comparison Of Silicates Of Sodium And Potassium As The Bonding Agent In Cold-Set Refractory Cements, Kenneth Frederick Sheckler

Bachelors Theses

"The insistent demand for higher grade refractories has resulted in the manufacture of a product which will withstand higher temperatures, have greater slag resistance, greater resistance to spalling action and deformation under load. These better grades of refractory materials have been developed as the result of extensive research on the part of the manufacturers. In order that these higher quality refractories may be employed with the best results, it is necessary that they be set with a refractory cement which also possesses these desirable properties. The commercial refractory cements may be divided into two classes according to their method of …
