Hydroxyapatite is a bioceramic that can be used as a denture material. Hydroxyapatite can be produced by synthesizing blood clam shells and eggshells as a source of calcium and (NH 4 ) 2HPO 4 , phosphate through hydrothermal methods. The hydroxyapatite samples were characterized by XRD and FTIR. The results of XRD analysis showed that the hydroxyapatite produced contained calcium carbonate (CaCO 3 ) and apatite carbonate type A. Hydroxyapatite has a hexagonal structure with lattice parameters a = 9.404 Å and c = 6.675 Å the resulting crystal size ranges from 10.19 nm to 57.29 nm. The results of the FTIR spectrum of the hydroxyapatite sample contained functional groups PO 4 3- , OH − and CO 3 2- which are functional groups of hydroxyapatite.
