Abstract

Hydroxyapatite (HAp) is a suitable bioceramic material for hard tissue replacement. In this present work HAp has synthesized by solid state reactions in temperature near 1250oC and it exhibits hexagonal crystal structure. HAp samples exhibited improvement in mechanical properties with increasing cold compaction pressure as well as recrushing operation. It also showed high resistance to surface reaction with the simulated body fluid. Surface morphology, pore volume, and particle size of the material have studied by Scanning Electron Microscopy, Brunauer-Emmett-Teller technique, and Particle Size Analysis. Chemical bonding present in the newly produced hydroxyapatite material was confirmed by Fourier Transform Infrared Spectrometry.
