PURPOSE: To easily provide at low cost the subject sintered compact excellent in reliability in its handling with high dimensional accuracy.
CONSTITUTION: In producing the subject monolithic sintered compact by heating and calcining a monolithic or laminated ceramic form, such a pressing force and/or restraint is applied, during the calcining, on part of its outer surface so as not to virtually cause sintering shrinkage for said part of the surface, and concurrently, the calcining shrinkage for the surface not applying such pressing force and/or restraint on (free surface) is compensated by controlling the creep developed in the material, thus controlling the final outer shape of the objective sintered compact. Thereby, the surface dimensional accuracy for part of the sintered compact can be relatively easily improved; and, in addition, the handleability, esp. mechanical reliability of the final sintered compact can be substantially improved.
