PRODUCTION METHOD OF SINTERED BODY OF BORON CARBIDE
PROBLEM TO BE SOLVED: To provide a sintered body of boron carbide excellent in discharge workability without damaging a physical property of the boron carbide, especially a density.SOLUTION: In a production method of a sintered body 1 of boron carbide, when forming the sintered body 1 of boron carbide by sintering a compact 4 formed by mixing particles 2 of boron carbide with a binder 3, under an atmosphere in which a conductive substance 5 is evaporated, sintering is performed after adjusting so that a condition for sintering the compact 4 satisfies a condition under which a sintered body enabling discharge machining can be obtained.SELECTED DRAWING: Figure 1
【課題】 炭化ホウ素の物性、特に密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】本発明の炭化ホウ素の焼結体１の製造方法は、炭化ホウ素の粒子２とバインダ３とを混合し且つ成形した成形体４を導電性物質５が気化した雰囲気下で焼結して炭化ホウ素の焼結体１を成形するに際しては、成形体４を焼結する際の条件を、放電加工が可能な焼結体が得られるような条件として焼結を行うことを特徴とするものである。【選択図】図１
