Zirconia sintered body, zirconia composition, zirconia pre-sintered body and preparing method thereof, and dental prosthesis
A method for preparing a zirconia composition comprises preparing a plurality of powders for lamination; the lamination powders containing zirconia, a stabilizer(s) suppressing phase transition of zirconia and a pigment(s) at respective different pigment content ratios, and laminating the lamination powders in a mold. In the laminating step, the mold is vibrated after at least two lamination powders are charged into the mold.
