METHOD FOR MANUFACTURING RED COLOR CERAMICS SINTERED BODY

摘要

The present invention relates to a manufacturing method of a red color ceramic sintered body, which comprises: preparing feedstock mixed with ZrO_2 powder and red pigment, and molding and debinding the mixture; preparing a red color stable sintered body by low-temperature sintering so as to prevent volatilization of red pigment during sintering the debinded body; and sintering a sintered body with an unavoidable decrease in sintered density, caused by the low-temperature sintering, by hot hydrostatic pressing again so as to stabilize red color and complete a red color ceramic sintered body with improved sintered density.
