Abstract (en)

A sintered body is produced by a process comprising suitably mixing powders with different average particle diameters and particle size distributions to prepare a starting raw powder with a tap density of 40% or more, kneading the obtained starting raw powder with less than 38% by volume of a binder, and injection molding the obtained mixture, debinding the resulting molded body in an atmosphere containing 1 to 30% of oxygen, and finally sintering the molded body in a reducing atmosphere. <IMAGE>
