Abstract: Calcium hydroxyapatite (HAp) powder was synthesized using waste anchovy fish bone through maceration process and subsequently heat treatment. The percent yield of obtaining product was 60%. On XRD analysis, the high purity of HAp phase was formed after immersing of each HCl and NaOH for 12 h and followed by heat treatmentat900°Cfor12h, resulting in thetriphasicmaterialofhydroxyapatite [Ca5(PO4)3OH], magnesium phosphate [Mg2(P2O7)] and whitlockite [Ca5Mg2H2(PO4)14], which contained weight percentage of 79:11:10 determined by the reference intensity ratio. The HAp powders had the degree of crystallinity equal to 98% and crystal size equal to 56 mm. The lattice parameter values of the HAp hexagonal crystal, a and c, were 9.4260 and 6.8845 Å, respectively. Moreover, the results of the FTIR analysis showed vibrational modes of at 569, 962, 1036, and 1189 cm−1, and the weak peak located at 3571 and 633 cm−1 corresponds to the vibration of ion in the HAp lattice. Meanwhile, there was also band at 371 cm-1 assigned to the bonding in calcium hydroxyl phosphates. This paper showed the great potential for the conversion of this by-product into highly valuable compounds.
