Book Synopsis Laboratory Evaluation of Graphite Crucible Coatings for Vacuum Melting Uranium by : Orville R. Magoteaux
Download or read book Laboratory Evaluation of Graphite Crucible Coatings for Vacuum Melting Uranium written by Orville R. Magoteaux and published by . This book was released on 1959 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxide and carbide coatings and methods of applying them to graphite crucibles were evaluated at the National Lead Company of Ohio on a laboratory scale. The objectives were to find a better crucible and mold coating than magnesia (MgO), which is currently used in the Metal Production Plant remelt operation, and a better method of application than brushing. The evaluation consisted of the vacuum-melting of slug uranium charges and derby uranium "as reduced" charges in graphite crucibles having different coatings, followed by studies of (1) the appearance of the coatings and (2) the metal quality (impurity levels) of the products.

The evaluation consisted of the vacuum-melting of slug uranium charges and derby having different coatings, followed by studies of the appearance of the coatings and the metal quality (impurity levels) of the products. Flame-sprayed magnesium zirconate (MgZro3) was determined to be the best coating evaluated. It limited the average carbon pickup to 73 ppm for derby uranium charges; with slug uranium, no pickup occurred. The flame-spray method provided a uniform coating thickness and virtually eliminated moisture and volatiles in the coatings. Studies showed that the flamesprayed magnesium zirconate contains a very small amount of volatiles and is not hygroscopic, but that 2500 deg F it is reduced slightly by graphite and co is released.

Book Synopsis A Contribution to the Study of the Reduction of UF4 to Uranium Metal by : Jovan Milosavljevich
Download or read book A Contribution to the Study of the Reduction of UF4 to Uranium Metal written by Jovan Milosavljevich and published by . This book was released on 1961 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reduction of small charges of uranium tetrafluoride with magnesium proved to be successful. By hand-tamping of UF4- Mg blend, tap densities ranging between3.1 and 3.4 g/cc were obtained. The reduction yields for these densities ranged from 72.79 to 93.71%. In the case of machine-compacted UF4-Mg blend having tap densities from 3.58 to 3.68 g/cc, reduction yields were higher, ranging between 91.45 and 97.2%. Machine-compacted blends gave much more uniform temperature distribution curves during the preheating period, as a result of higher tap densities. The best yields were obtained by firing a machine- compacted blend containing 5% Mg excess at a furnace temperature of 650 deg C, giving an average crude metal yield of 96.3%. However, the high carbon content of 174 ppm in the crude uranium biscuits obtained by compacts reduction, as a result of hydrocarbon binder presence, appeared to be a disadvantage. Attempts were also made to demonstrate the initiation of the reduction reaction at temperatures lower than 500 deg C by taking x-ray-diffraction patterns of the samples of the UF4-Mg charges heated up to various temperatures.
