Abstract
Methods for reducing carbon contamination when melting highly reactive alloys involving providing a graphite crucible having an interior, applying at least a first protective layer to the interior of the graphite crucible, placing a highly reactive alloy into the crucible having the first protective layer, and melting the highly reactive alloy to obtain a melted alloy having reduced carbon contamination.
