METHOD FOR SINTERING GREEN COMPACT

摘要

PROBLEM TO BE SOLVED: To improve the yield of a product by suppressing adhesion force after sintering a green compact in a lamination state. SOLUTION: Green compacts 1A-1F are brought into contact one another by end faces 3 and 3 that oppose up and down for lamination. The green compacts 1... are arranged while a peripheral surface is glued in X-Y directions, and six layers are piled up in up/down directions. The green compacts 1... being overlapped up and down are shifted by approximately 1/3-1/2 of a diameter D of the end face 3 in an X direction from a coaxial position from the end face 3 of the green compact at a lower side, and the upper green compact 1 is overlapped, thus reducing a contact area. Since the green compact 1 shrinks due to sintering, the contact area of the end faces 3 and 3 is further reduced and each adhesion force becomes small.
