1. A zirconia material manufacturing method comprising:
dispersing hydroxyapatite powder in water to prepare a slurry having a hydroxyapatite powder concentration of 1%;
dipping zirconia in the slurry to form, on the zirconia, a coating layer containing hydroxyapatite; and
after forming the coating layer, performing a thermal treatment for the coating layer at a temperature within a range of 1050° C. to 1250° C., wherein
the forming the coating layer includes a thickness of the coating layer being 0.5 μm, and
a surface of the zirconia to be dipped in the slurry is a polished surface.
