Abstract

PREPARASI NANOKRISTALIN HIDROKSIAPATIT UNTUK SCAFFOLD REKAYASA JARINGAN TULANG. Telah dilakukan sintesis dan karakterisasi nanopartikel Hidroksiapatit (HA) menggunakan metode presipitasi. Hasil pencampuran serbuk Ca(OH)2 dan cairan H3PO4 dengan perbandingan mol sebesar 10 : 6 selanjutnya dikalsinasi pada suhu bervariasi sampai dengan 900 oC masing-masing selama 3 jam. Hasil refinement pola difraksi sinar-X menunjukkan bahwa hidroksiapatit hasil sintesis dengan berbagai suhu kalsinasi merupakan fasa tunggal Ca10(PO4)6(OH)2 yang memiliki struktur heksagonal (P63/m). Berdasarkan hasil refinement diperoleh bahwa seiring dengan semakin rendahnya suhu kalsinasi HA maka diperoleh volume, kerapatan atomik dan derajat kristalinitas yang semakin menurun dan ukuran kristalit yang semakin kecil. Disimpulkan bahwa pada suhu kalsinasi HA hasil sintesis terendah, maka diperoleh volume, kerapatan atomik dan derajat kristalinitas paling rendah dengan ukuran kristalit paling kecil.

ABSTRACT
PREPARATION OF HYDROXYAPATITE NANOCRYSTALINE FOR SCAFFOLD BONE TISSUE ENGINEERING. The synthesis and characterization of hydroxyapatite nanoparticles by using precipitation method have been carried out. Hydroxyapatite samples were prepared by mixing Ca(OH)2 powder and H3PO4 liquid with a mole ratio of 10 : 6. The samples were calcined at temperatures varying from 100 - 900°C, each for 3 hours. The refinement results of X-Ray Diffraction patterns showed that all samples are single phase of Ca10(PO4)6(OH)2. The Ca10(PO4)6(OH)2 and has a hexagonal structure (P63/m). Based on the refinement results, increasing the calcination tempertatures of HA from 100 to 900°C, HA exists in higher volume, atomic density and crystalinity, as well as smaller of crystalites diameter. It is concluded that at the lowest calcination temperature of HA, the lowest volume, atomic density and crystallinity and the diameter of crystallites as well.
