Abstract:
1. A method for producing apatite, comprising: preparing an apatite material solution containing metal atoms that absorb visible light and other metal atoms and not containing undoped apatite where the content of the metal atoms that absorb visible light is not less than 0.5 mol % and not more than 3 mol % with respect to the whole metal atoms contained in the solution; coprecipitating components contained in the apatite material solution so as to form doped apatite; drying the formed doped apatite; and subsequently firing the formed doped apatite at a temperature of not lower than 500° C. and not higher than 700° C., wherein: the metal atoms that absorb visible light are atoms of at least one kind of metal selected from the group consisting of Cr, Co, Cu, Fe and Ni, and the other metal atoms further contain metal atoms of at least one kind of metal selected from the group consisting of Ti, Zr and W as metal atoms that absorb UV light.
