dc.description.abstractFabrication and characterization of hydroxyapatite from Geloina coaxans and H3PO4 as precursors have been done. The main of chemical composition from Geloina coaxans shell was CaCO3, this material can be used as calcium source on fabrication of hydroxyapatite. Calcium oxide was obtained by calcination CaCO3 at 900oC for 12 hour. Synthesis of HAp was done with molar ratio of precursor 1,67 and pH of solution was adjusted at 11 with different stirring times (4 and 6) hours. Hydroxyapatite synthesized was characterized using XRD instrument, and the result proved that HAp nanopowder can be obtained successfully with stirring time for 4 hour with specific peak at 2θ = 31.7. Using Schererr equation, particle size of HAp powder was 26.42 nm. FTIR analysis was also done to determine functional group of HAp. The FTIR spectra of HAp powder obtained show there were characteristics band exhibited in sample spectra. Thermal analysis and particle size analysis were also investigated with TG-DTA and PSA instruments respectively. Analysis morphology by SEM revealed nearly uniform spherical morphologyen_US
