[ABSTRAK
Hidroksiapatit (HA) mempunyai peran penting dalam bidang medis karena komposisi kimia dan strukturnya yang mirip dengan tulang manusia. Material ini disintesis melalui metode hidrotermal dengan prekusor Ca(NO3)2, CaO dan NH3PO4. Variasi temperatur hidrotermal pada 150 ̊C dan 300 ̊C, temperatur sintering pada 900 ̊C selama 3 jam. Endapan yang diperoleh diuji dengan XRD dan SEM-EDX. Morfologi partikel hasil karakterisasi SEM berbentuk batangan memanjang dan melingkar teraglomerasi dan hasil uji EDX menunjukkan rasio Ca/P yang lebih besar dari 1.67. Uji XRD menunjukkan adanya fasa kalsium difosfat, fluorapatit dan apatit karbonat tipe- A di dalam endapan yang meningkatkan rasio Ca/P.ABSTRACT

This material was synthesized through hydrothermal method using Ca(NO3)2, CaO and NH3PO4. Hydrothermal temperature varied on 150 ̊C and 300 ̊C, sintering temperature on 900 ̊C for 3 hours. Sample was characterization by XRD and SEM-EDX. Morphology observed by SEM is agglomerated round- spherical- shape particle with Ca/P ratio more than 1.67 measured by EDX. Calcium diphospate, fluorapatite and carbonated type- A presence is observed by XRD.;Hydroxyapatite (HA) posseses significant role in medical application due to its similarity in chemical and structure to human bones.
