DIE MATERIAL SUPERIOR IN MOLD RELEASING PROPERTY IN ELECTRIFICATION SINTERING, AND COMPACTED MEMBER USING IT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a compacted member with high precision by improving a die releasing property in electrification sintering, and to provide the compacted member. SOLUTION: This method for producing a compact using an electroconductive ceramic containing zirconium oxide in a contacting part with the compact, in electrification sintering, and a material having different electrical characteristics from those of the ceramic between the ceramic and an electrode, to prevent destruction of a die caused by a thermal shock and copy a surface fine form of the die onto the compact with high precision by a high applied pressure. The compact can be easily separated from the die without using a mold releasing material, but by using a phenomenon that oxygen in zirconium oxide is migrated by the electrification and is released from the die.
