<P>PROBLEM TO BE SOLVED: To provide: a method for producing ceramic granules capable of suppressing shape collapse when they are formed; a method for producing a ceramic formed body, by which the shape collapse can be suppressed and a formed body having a high and uniform density can be obtained; and a method for producing a ceramic sintered compact, by which the shape collapse can be suppressed and a ceramic sintered compact having a high and uniform density can be obtained. <P>SOLUTION: In the method for producing the ceramic granules, comprising preparing a slurry by irradiating a raw material for ceramic granules containing water, a ceramic powder, and an anionic surfactant with an ultrasonic wave and then granulating the slurry, the temperature of the slurry is kept at a temperature of ≤45°C during irradiation with the ultrasonic wave. The ceramic formed body is obtained by forming the obtained ceramic granules, and further, the ceramic sintered compact is obtained by sintering the obtained formed body. <P>COPYRIGHT: (C)2008,JPO&INPIT |
