MANUFACTURING METHOD FOR SINTERED BODY AND SINTERED BODY
To provide a novel technique for improving density of a sintered body.SOLUTION: A manufacturing method for a sintered body according to some aspect of the present disclosure is the manufacturing method for a sintered body in which prescribed electrical field is applied after raising the temperature of ceramic compressed powdery body up to a prescribed temperature. The prescribed temperature is a temperature higher than a flash sintering temperature in which electrical current passing in the ceramic compressed powdery body is abruptly increased in raising the temperature while applying the electrical field to the ceramic compressed powdery body. The prescribed electrical field is an electrical field in the range where the phenomenon occurs in which the electrical current passing in the ceramic compressed powdery body is abruptly increased in raising the temperature while applying the electrical field to the ceramic compressed powdery body.SELECTED DRAWING: Figure 1
【課題】焼結体の密度を向上する新たな技術を提供する。【解決手段】本開示のある態様の焼結体の製造方法は、セラミック圧粉体を所定温度まで昇温した後に、所定の電界を印加する焼結体の製造方法であって、所定温度は、セラミック圧粉体に電界を印加しながら昇温した場合に該セラミック圧粉体に流れる電流が急激に増加するフラッシュ焼結温度よりも高い温度であり、所定の電界は、セラミック圧粉体に電界を印加しながら昇温した場合に該セラミック圧粉体に流れる電流が急激に増加する現象が生じる範囲の電界である。【選択図】図１
