Abstract
Self-resistance heated, electrically conductive, refractory evaporating boats containing titanium diboride can be reclaimed for reuse. If there is aluminum adhering to the boats, they are first leached in hot caustic solution to remove the aluminum. After rinsing and drying, the boats are ground to powder which is then screened. The screened powder is used to manufacture new boats.
