The invention relates to a black zirconia ceramic material as well as a preparation method and product of black zirconia ceramics. The black zirconia ceramic material is prepared from the following components in percentage by weight: 80 to 95 percent of zirconia; 2.5 to 5 of yttrium oxide; the balance of a black coloring material. The black coloring material is prepared from the following components in percentage by weight: 0 to 40 percent of iron oxide, 0 to 30 percent of chromium oxide, 10 to 30 percent of cobalt oxide, 0 to 10 percent of manganese oxide, 0 to 10 percent of nickel oxide, 5 to 30 percent of aluminum oxide, 0 to 6 percent of zinc oxide, and 0 to 5 percent of silicon oxide, wherein the weight percentage of the iron oxide, the chromium oxide, the cobalt oxide, the manganeseoxide, the nickel oxide, the aluminum oxide, the zinc oxide and the silicon oxide is a percentage of the total weight of the black coloring material. The preparation method of the black zirconia ceramics adopts casting molding and warm isostatic pressing process according to the material characteristics and adopts appropriate rubber discharging and sintering processes, and finally, the black zirconia ceramics are not only pure in color and high in blackness after being sintered at a higher temperature, but also have the characteristics of high strength, good toughness and the like.
