Coated graphite crucible

摘要

The present invention provides a coating for an article for use with molten metal, the coating obtainable by depositing the coating on the article by magnetron sputtering. Unbalanced magnetron sputtering is preferred. The molten metal may comprise molten uranium and/or molten uranium salt. A coating deposited by magnetron sputtering is particularly effective for improving the performance and lifetime of graphite crucibles for containing molten uranium metal and/or molten uranium salts.
