A method for manufacturing hydroxyapatite is provided, which uses water-heat by controlling kind and concentration of the phosphate solution. A method for manufacturing hydroxyapatite using shell comprises: a step of washing and dyring shell; a step of pulverizing the shell; a step of putting the pulverized shell into the phosphate solution and performing water-heat process; and a step of filtering the water-heat processed shell and drying the shell. The hydroxyapatite having various crystallizations can be obtained by the difference of the solubility of the calcium ion within the shell according to the size of shell and dissolution velocity. |
