The aim of this study was to explored the effects of Fe_2O_3 and Bi_2O_3 on the color properties of a 3Y-TZP zirconia ceramics for dental application. Pigmented dental ZrO_2 powders were prepared by mixing different concentration of Fe_2O_3 and Bi_2O_3, also in their combinations with 3Y-TZP powders. The mixture was compacted by isostastic pressure, then densely sintered. Color parameters were measured by Minolta cm~2600d spectrophotometer. XRD was used to exam the structure of colored 3Y-TZP. Experimental results showed that the hue of the materials shift from yellow-green to yellow-red with the increasing concentration of the Fe_2O_3 and Bi_2O_3 Combined use of Fe_2O_3 and Bi_2O_3 could further decrease the L~* value, which color scope was suitable for dental color matching. The XRD spectra showed only tetragonal phase was detected.
