Abstract
A crucible for containing metal to be evaporated for vacuum deposition is manufactured by winding refractory metal wire into the shape of a helical basket coil. The coil is electrophoretically coated with a primer coat of alumina and is then flame or plasma sprayed with alumina to form the crucible.
