  • Method of Manufacturing a Zirconium Dioxide Green Body with Color and Translucency Gradients
    Publication number: 20220289632
    Abstract: The invention relates to a method of manufacturing a ceramic molding, comprising the following steps: a) providing three or more ceramic powder layers that are arranged in layers, one on top of the other, to form a compression-molded element and sintering the compression-molded element obtained in step b) to form a ceramic molding, characterized in that the ceramic powder layers have different compositions, each ceramic powder layer comprising a mixture of at least two different base powders and each base powder containing at least 80 wt. % ZrO2 and at least 0.02 wt. % Al2O3, each weight amount being relative to the total weight of the constituents of the base powder.
