Abstract

Hydroxyapatite Material: Synthesis by Using Precipitation Method from Limestone

Author(s): Novesar Jamarun, Sri Elfina, Syukri Arief, Akmal Djamaan and Mufitra

Limestone is made of calcium carbonate. An Attempt is made to convert calcium carbonate to calcium oxide for precursor of calcium in hydroxyapatite synthesis. Phosphate was from hydrogen phosphate [H3PO4]. Diammonium hydrogen phosphate [(NH4)2HPO4] were used as precursors and ammonia was used as the agent for pH adjustment. The synthesized samples was characterized by Fourier Transform Infra Red (FTIR), X-ray Difraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). Result show that hydroxyapatite with calcium oxide 1 M was give fine produce. Analysis of BET, result show Intercept of 1.174e+01 and slope of 250.030, total pore volume obtained from hydroxyapatite 3.881e-02 cc/g and average pore radius of 5.83490e+01 Å.
