Preparation and Characterization Nanoparticle Calcium
The Nanoparticle Calcium Oxide (NCO) was prepared using the ball milling method. This study aims to make NCO as a raw material for hydroxyapatite synthesis. The NCO was characterized using Fourier Transform InfraRed (FTIR), XRay Diffraction (XRD), and Scanning Electron Microscope (SEM). Characterization using FTIR shows that NCO has functional groups OH, CO32 and PO43
