ABSTRACT:
A method of reclaiming precious metal incidentally sputtered into vacuum chamber walls, fixtures, and the like. The incidentally sputtered precious metal is reclaimed by grinding it into a metal powder that is useful as an electrical conductor in a cermet ink. Power can also be made by pulverizing the principally sputtered metal too.
