  • The setting of a presintering temperature is carried out on the basis of the Vickers hardness of the presintered compact in the method for producing a ceramic sintered compact comprising presintering a formed compact composed of a ceramic powder and a sintering assistant, then machining the presintering compact and subsequently sintering the machined compact. The Presintering temperature is preferably set at a temperature so as to provide 213-230 Hv Vickers hardness of the compact for presintering. Furthermore, the presintering temperature is preferably within the range of 1,300-1,450$^{\circ}C$.
