【 摘 要 】

Fish bone waste has long been used in research laboratories that make it necessary for the program to transfer the knowledge to the community in order to improve its usefulness. Fish bone is a form of waste generated from the fish crackers processing industries that like the highest content of calcium hydroxyapatite (HA or HAp). In the bones, the minerals are mainly deposited in the form of calcium phosphate compounds with the greatest majority existing as apatite and only a small amount of the most carbonate containing apatites. Fish bone was converted to hydroxyapatite by heat treatment method at different temperature sand for different conversion durations. Based on the result characterization (at temperature of 1100 °C by FTIR) only the phosphate is exist which is at 1026 cm-1which almost has no impurities that the coumpound HA at high temperatures and smaller particle will be produced hydroxyapatite which is the particle size using 25 μm.
