PROBLEM TO BE SOLVED: To provide a simple method for manufacturing a sintered compact and the sintered compact which is manufactured by such manufacturing method and is usable for, for example, artificial bones, dental roots, or the like. SOLUTION: This method for manufacturing the sintered compact has a process step of putting a slurry 1 contg. hydroxy-apatite which is a synthesize material obtained by mixing, for example, calcium hydroxide (first raw material) and an aqueous phosphoric acid (second raw material) solution and reacting these raw materials into a mold 10 and applying a centrifugal force to the slurry, thereby obtaining a molding 2 and a process step of obtaining the sintered compact 3 by firing the molding 2. The number of revolutions (number of centrifugal revolutions) of the mold 19 is continuously or stepwise changed, by which the density of the molding 2 can be changed in the direction where the centrifugal force acts. |
