PRODUCTION METHOD OF ZIRCONIA SINTERS

摘要

A manufacturing method of sintered zirconia of a core-shell structure is provided to manufacture efficiently and quickly zirconia-sintered body having a shell section of the cubic having high hardness and a tetragonal core unit having high tenacity by sintering quickly the molding product consisting of the zirconia powder at a state of being coated by the apatite system material. A manufacturing method of sintered zirconia of a core-shell structure comprises steps of: coating a molding product which is manufactured to zirconia powder to an apatite typed material; and sintering the molding product onto which the apatite system material is coated.
