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.
