Abstract:
1. A method for producing a regenerated target, comprising: a powder filling step of disposing a spent target made of a metal sintered body or a composite sintered body of a metal and a metal compound in an inner space of a frame jig having the inner space piercing in a uniaxial direction, and filling the inner space with a raw material powder for a target made of a metal or made of a metal and a metal compound to cover an erosion part side of the spent target with the raw material powder for a target; a cushioning-material disposition step of disposing a deformable cushioning material made of an inorganic fiber so that the raw material powder for a target with which the inner space has been filled in the powder filling step is sandwiched between the spent target and the cushioning material; and a sintering step of pressing the raw material powder for a target with which the inner space has been filled and the spent target in the uniaxial direction through the cushioning material disposed in the cushioning-material disposition step and sintering them, wherein in the cushioning-material disposition step the cushioning material is disposed so that an amount of the cushioning material to be disposed is larger in a thicker region of the layer of the raw material powder for a target covering the erosion part side of the spent target in the powder filling step.
