METHOD FOR PRODUCING CERAMIC SINTERED COMPACT
To provide a method for producing a ceramic sintered compact capable of producing a ceramic sintered compact having excellent strength and also having a uniform composition in a short time.SOLUTION: The surface of a base material 4 is coated with an ink 5 including a first powder 1 made of ceramic and a second powder 2 essentially consisting of a metallic element whose volume increases by oxidation by an inkjet method. Next, a suspension layer 6 is sintered using thermal plasma to form a sintered layer 7 made of ceramic. By repeatedly performing the coating step and heat treatment, a ceramic three-dimensional object 8 having high hardness is fabricated in a short time at high precision.SELECTED DRAWING: Figure 1D
【課題】短時間で強度に優れかつ均一な組成のセラミックス焼結体を製造できるセラミックス焼結体の製造方法を提供する。【解決手段】セラミックスからなる第１粉体１と、酸化によって体積が増加する金属元素を主成分にした第２粉体２とを含むインク５を基材４の表面にインクジェット法により塗布する。次に、熱プラズマを用いて、懸濁液層６を焼結し、セラミックスからなる焼結層７を形成する。このような塗布工程と熱処理を繰り返し行うことにより、短時間で高精度に、硬度の高いセラミックス立体物８を造形する。【選択図】図１Ｄ
