MANUFACTURING METHOD OF COMPOSITE SINTERED BODY, MANUFACTURING METHOD OF COMPOSITE MOLDED BODY, AND COMPOSITE SINTERED BODY AND COMPOSITE MOLDED BODY

摘要

PROBLEM TO BE SOLVED: To enhance the dimensional precision of a composite sintered body and to improve productivity, on the occasion of manufacturing the composite sintered body having at least first and second phases and having a boundary provided between the first and second phases.;SOLUTION: The composite sintered body having at least the first and second phases and having the boundary provided between the first and second phases is manufactured. On the occasion of obtaining a composite molded body comprising the first and second phases, a slurry containing a powdered inorganic material that can be sintered, a dispersion medium and a gelling agent is cast in a mold and solidified by gelatinization. Thereby at least the first phase is molded. The composite sintered body is obtained by sintering the composite molded body subsequently.;COPYRIGHT: (C)2004,JPO
