The Determination Of The Alumina Content In Diaspore And High Alumina Clays, W. D. Keller Jan 1930

The Determination Of The Alumina Content In Diaspore And High Alumina Clays, W. D. Keller

Bachelors Theses

"The determination of the alumina in diaspore and kindred high alumina clays has been a problem which has attracted the interest of ceramists and chemists ever since a sample of Missouri diaspore was first sent for analysis to the laboratories of the Missouri School of Mines and Metallurgy in 1917...It is the writer's intention to review in this paper the various published methods for the determination of alumina in high alumina clays and to present a new indirect one that after some months' use in industrial practice, fulfills, in some measure at least, the need outlined above"--Introduction, page 1 -2.

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Degree Of Pressure, Physical Character Of Mix Ingredient, And The Moisture Content Of The Mix, George Ava Page Jan 1930

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Degree Of Pressure, Physical Character Of Mix Ingredient, And The Moisture Content Of The Mix, George Ava Page

Bachelors Theses

"In the manufacture of dry press brick, the final grinding and tempering of the clay is usually done in a dry pan. The next operation is forming the ware by means of applying pressure, either mechanical or hydraulic. The actual pressure that a brick is subjected to in a mechanical press has always been a question...The purpose of this investigation was to determine what effect would be imparted to the brick by varying the forming pressure and keeping the water content constant, and what effect would be imparted by varying the water content and keeping the forming pressure constant, on …

Florida Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, Hugo Logan Harrod Jan 1929

Florida Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, Hugo Logan Harrod

Bachelors Theses

"The purpose of this investigation was to utilize a large percentage of Florida Plastic Kaolin in a new sanitary ware casting body. Such a body, when worked out to be satisfactory, could be produced at a lower cost than those bodies being used in American plants at present. This particular plastic kaolin is available in large quantities in the southeastern portion of the United States. It is the intention of this work to substitute this American clay for the more costly imported English China Clay now being used in sanitary ware casting bodies"--Introduction, Purpose of the Investigation, page 1.

A Study Of Chrome And Diaspore Mixes, Harlow Guy Jones Jan 1929

A Study Of Chrome And Diaspore Mixes, Harlow Guy Jones

Bachelors Theses

"The high refractoriness of both chrome and diaspore make them very valuable to the refractory industry. Chrome ore has been experimented with since 1879 and used in brick form since 1886. Diaspore on the other hand, has just recently been recognized as a refractory After going through all the available literature on the subject I have been unable to find any mention of any work carried on in which mixtures of chrome and diaspore were used"--page 1.

Cone Deformation Eutectics Using Sodium Chloride, Dolomite, And Alpite Rock, William K. Schweickhardt Jan 1928

Cone Deformation Eutectics Using Sodium Chloride, Dolomite, And Alpite Rock, William K. Schweickhardt

Bachelors Theses

"Heterogeneous Equilibrium, alone, is an extensive study in itself and no discussion of it will be given here. It is known from this study that different phases are formed in various systems, the system consisting of two or more components. Some systems form an eutectic, which is a mixture of two solids which combine to form a liquid at a lower degree of temperature than either of the milting points of the two solids, as shown in the two component system of KCl and LiCl¹; some systems form solid solutions in which there is no eutectic formed, and the solids …

Difference In Pyrometric Cone Equivalent Between Raw And Calcined Clay, Charles Alfred Freeman Jan 1928

Difference In Pyrometric Cone Equivalent Between Raw And Calcined Clay, Charles Alfred Freeman

Bachelors Theses

"In a recent survey of the refractories field with particular respect to the Pyrometric Cone Equivalent of different clays it was suggested that a difference in the P. C. E. value of clays might be found due to different stages of heat treatment that these clays had previously undergone. At present there is considerable apparent lack of information regarding this problem. It is evidenced largely in the samples of clay sent into commercial testing and research laboratories by manufacturers who are attempting to develop definite properties from a given clay or clay body. There is a large difference in the …

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler Jan 1925

The Properties Of The Fire Clays Used For The Manufacture Of Zinc Retorts, Adolph Harmon Kuechler

Masters Theses

"The ultimate object of this refractories investigation is to develop a body for zinc retorts, or changes in the method of their manufacture, that will result in better retorts than the ones now in use. In doing this, the question of permissible cost must, at all times, be kept in mind. The immediate object of the present phase of this investigation, of which this thesis covers only a part, is to determine the physical and chemical properties of the refractories (fire clays, grogs, bodies, etc.) now used for the manufacture of zinc retorts. This will be a basis for later …
