METHOD FOR PRODUCING CERAMIC STOCK SPHERE
PROBLEM TO BE SOLVED: To produce a boron carbide sintered body excellent in electric discharge processability without impairing the hardness of boron carbide.SOLUTION: The inventive ceramic stock sphere 1 production process comprises: a mixing step of mixing a material to be sintered 2 and a binder 3 to prepare a mixture 6; an injection step of injecting the mixture 6 mixed in the mixing step into a mold 8 having a sphere shaped molding part 7 to produce a sphere shaped molded body 5; and a sintering step of sintering the molded body 5 obtained in the injection step to produce a ceramic stock sphere 1. Note that boron carbide is preferably used for the material to be sintered 2, and it is preferable to sinter the boron carbide molded body 5 in an atmosphere in which conductive material is vaporized.SELECTED DRAWING: Figure 1
【課題】 炭化ホウ素の硬度を損なうことなく放電加工性に優れた炭化ホウ素の焼結体を得る。【解決手段】本発明のセラミック素球１の製造方法は、被焼結材料２とバインダ３とを混合して混合物６を得る混合工程と、混合工程で混合された混合物６を、球状の成形部７を備えた金型８内に射出して、球状の成形体５を得る射出工程と、射出工程で得られた成形体５を焼結することでセラミック素球１を得る焼結工程と、を備えている。なお、被焼結材料２には炭化ホウ素が用いられているのが好ましく、導電性物質が気化した雰囲気中で炭化ホウ素の成形体５を焼結するのが好ましい。【選択図】図１
