Abstract

Hydroxyapatite is a synthetic substance in the form of microspheres composed of calcium and phosphate, present in human bones and tooth enamel. The objective of the work was to synthesize hydroxyapatite, from the solution of calcium nitrate and diamonic phosphate by the method of precipitation and heat treatment, obtaining the hydroxyapatite in powder form. To study its structural evolution, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Raman spectroscopy were used. The results show that the hydroxyapatite nanocrystalline can be successfully produced by the precipitation technique from raw materials.

Is a bioceramic widely studied due to their chemical similarity to component mineral from bone. in addition, it is biocompatible, non exhibits effects cytotoxic, bioactive and thermodynamically stable in the fluid body, as well as with hard tissue, skin and muscle, which places as an attractive material for a wide range of applications in the field biomedical

Summary

Introduction

The biomaterials have been getting one large attention by part of the scientific community. The first method can be divided into three groups: precipitation, hydrothermal technique and hydrolysis of other calcium phosphates (Aoki, 1991). It is expected that HAp when in nanometric character has better bioactivity than larger crystals (Stupp & Ciegler, 1992). The use of precipitation processes for the synthesis of HAp has become an important research objective ( Han, et al 2004). Natural HAp crystals exhibit hexagonal conformation and have a single cell with network parameters: a = b = 9.389 Å and c = 6.869 Å, α = β = 90 and γ = 120 (Brundavanam et al, 2013).
