A Comparative Study Of The American Society For Testing Materials Spall Test And The Federal Specifications Spall Test, Justus Jordan Beinlich
A Comparative Study Of The American Society For Testing Materials Spall Test And The Federal Specifications Spall Test, Justus Jordan Beinlich
Bachelors Theses
"Commercial brands of fireclay brick will be tested with both the American Society for Testing Materials and the Federal Specifications Spall Tests in order to determine whether the two tests are consistent in the indication of resistance to spalling. It is suggested that the properties of a refractory affecting thermal spalling are reversible thermal expansion, elasticity, heat transfer, plastic flow, and strength. It is hoped that it will be possible to explain the discrepancies that may arise in the results of this work in terms of the above physical properties or else find a reasonable agreement between the two tests"--Introduction, …
The Effect Of Reheating Certain Fire Brick On Pyrometric Cone Equivalents, Francis J. Louney
The Effect Of Reheating Certain Fire Brick On Pyrometric Cone Equivalents, Francis J. Louney
Bachelors Theses
"In a recent survey of the refractories field, especially with respect to the softening point of fire brick, it was suggested to the author that the possibility of reheating certain fire brick, according to the specifications given by the American Society for Testing Materials, might produce a difference in pyrometric cone equivalent from that of the original or unreheated sample. At present, there is considerable lack of knowledge regarding the problem, as evidenced by the utter lack of literature on the softening point resulting from the reheating of fire brick"--Introduction, leaf 1.
The Effect Of Variations In The Rate Of Heating On The P.C.E. Value Of Clays, Kenneth Emerson Evans
The Effect Of Variations In The Rate Of Heating On The P.C.E. Value Of Clays, Kenneth Emerson Evans
Bachelors Theses
"Softening temperature of ceramic materials vary with the rate of heating. Recently much discussion has centered about the proper rate of heating of cones in the P.C.E. test. The most obvious reason for the discussion is that the cones are affected by the rate of heating when tested alone for softening temperature"--Introduction, page 1.

Aventurine Glazes, Felix Fraulini
Bachelors Theses
"The object of this study was to notice the effect produced upon the crystalline growth in the glaze by the variation of B₂O₃, Fe₂O₃, and SiO₂, and to notice the effect of cooling upon the crystalline growth in the glaze"--Scope of Investigation, leaf 3.
Study Of The Substitution Of Barite For Barium Carbonate In A Whiteware Body Suitable For Brick Manufacture, Charles Edward Achuff
Study Of The Substitution Of Barite For Barium Carbonate In A Whiteware Body Suitable For Brick Manufacture, Charles Edward Achuff
Bachelors Theses
"Some years ago a method of manufacturing white brick from Georgia Kaolin and apatite rock was developed. This was successful for supplying an attractive white brick to the southern trade, until difficulties were encountered in securing apatite rock of sufficiently high grade to insure the continuance of manufacture of the brick...With the foregoing facts at hand, a study was made of the utilization of an auxiliary flux to replace the apatite rock. A commercial brick was developed, wherein eight (8) per cent of this flux, with forty-two (42) per cent potters flint and fifty (50) per cent Georgia Kaolin was …
The Replacement Of Calcium Carbonate With Calcium Chloride And Calcium Fluoride In A Whiteware Body, Charles Richard Rosenbaum
The Replacement Of Calcium Carbonate With Calcium Chloride And Calcium Fluoride In A Whiteware Body, Charles Richard Rosenbaum
Bachelors Theses
"In the steel industry it is a common metallurgical practice to add fluospar sic (CaF₂), to a slag to render it more fluid. Ladoo states that the fluospar sic , thus added, forms eutechtics with the silica, alumina, calcium and barium sulfates, rendering them more fusible. The fluospar sic does not decompose, but forms solutions or eutechtics with other substances in the slag. He further states that calcium chloride (CaCl₂) has been used for this purpose but is apparently not as active, necessitating larger quantities per charge. It is also probably more expensive. Calcium carbonate (CaCO₃) is commonly used as …
