ABSTRACT:
Granulated powder for molding produced by granulating material powder, whose variation factor (the standard deviation of strength/average strength) of the compressive strength of each granular particles composing granulated powder is 0.3 or less. By using granulated powder for molding of the present invention, sintered bodies with preferred properties, in particular with high strength can be produced stably.
