    摘要: The method for manufacturing a sintered piece comprises preparing a molded piece of a composite including calcium phosphate compound such as hydroxyapatite, and baking the molded piece in an oxygen atmosphere to obtain the sintered piece. The oxygen concentration of the oxygen atmosphere is controlled to be not less than 25 vol %, and the relative humidity of the oxygen atmosphere is controlled to be below 30% RH. The baking is performed for 30 minutes to 8 hours at a temperature not less than 1000° C. and below a temperature at which thermal decomposition of the calcium phosphate occurs.
