The invention relates to a preparation method of pink zirconia ceramic. The preparation method comprises the following steps: with zirconia powder as a raw material of a ceramic matrix, adding erbium oxide powder to the zirconia powder to be used as a colorant and adding a binder to form a mixed material; preparing a ceramic body by using the mixed material; and carrying out multi-stage sintering treatment on the ceramic body to obtain a pink zirconia ceramic product, wherein the multi-stage sintering treatment at least comprises the following stages: firstly sintering for 7-9h at the temperature of room temperature to 600 DEG C, then sintering for 4-8h at the temperature of 600 DEG C-1200 DEG C, and then sintering for 6-8h at the temperature of 1200 DEG C-1500 DEG C. By utilizing the preparation method of the pink zirconia ceramic, zirconia can be stably colored to pink by pigment on premise of ensuring complete compactness of sintering of zirconia, and low manufacturing cost is maintained simultaneously.
