Abstract
Disclosed in this specification is a process for refurbishing a spent sputtering target. The process includes the step of applying sufficient heat and axial force to the filled sputtering target to hot press the filled sputtering target such that the powdered metal fuses with the un-sputtered metal, producing a refurbished target. The process may be used to refurbish precious metal targets, such as ruthenium targets.
