Analisis Biomaterial

Analisis BiomaterialSynthesis and Characterization of Hydroxyapatite Powder by Sol-Gel Method for Biomedical ApplicationINTRODUCTION Hydroxyapatite (Ca10 (PO4) 6 (OH) 2, HA) merupakan bahan anorganik penting yang telah menarik perhatian para peneliti yang terkait dengan bidang biomaterial dalam beberapa tahun terakhir.Karena kimia dan kesamaan struktur dengan fase mineral tulang dan gigi, HA banyak digunakan untuk perbaikan jaringan keras.

EXPERIMENTAL PROCEDURE2.1. Powder Preparation :Reagen-1:Ca(NO3)2.4H2O(calcium nitrate tetrahydrate)Reagen-2:P2O5(phosphoric pentoxide

EthanolStir the solution for 10 15 hFormation gelNext..EXPERIMENTAL PROCEDURENextDrying : use Oven in 80 celcius deg.Heat treatment: 400 celcius deg.Heat treatment: 700 celcius deg.Hydroxyapatite,HAEXPERIMENTAL PROCEDURE2.2. Powder Characterization:The crystallographic phases of HA powder was determined by X-ray diffractometer (XRD)The presence of functional groups was confirmed by using Fourier transform infrared spectroscopy (FTIR)EXPERIMENTAL PROCEDURE2.2. Powder Characterization:The surface morphology and microstructural features of the synthesized HA powder with elemental composition was studied and evaluated by Field Emission Scanning Electron Microscope (FE-SEM)EXPERIMENTAL PROCEDUREThermo gravimetric analysis (TGA) equipped with differential thermal analysis (DTA) of the powder was done with (Perkin Elmer Pyris Diamond) thermal analyzer in air atmosphere at a heating rate of 100C/min up to 12000C.
