Generally, these analysis techniques generate a structural model ‘ab initio’ (i.e. To achieve this goal, several analysis techniques have been developed to resolve the diffraction data since the publication of the original Rietveld method in 1969. For these solids, it is necessary to use the powder diffraction technique and then analyse the resulting data to determine the materials structure. Although single crystal X-ray diffraction is a useful technique for determining crystal and molecular structures, there are many solids that can only be prepared as microcrystalline powders and therefore cannot be studied using the single crystal diffraction technique. Introduction The determination of the crystal structure of a new material is frequently the prerequisite for the rational understanding of the solid state properties of a material. The resultant slurries were then thermally treated in radiant tube furnace to produce nanometre scale particles with a mean diameter of 30 nm.ġ. During the process the calcium phosphate ratio was set at 1.67 and the pH was maintained at 9. The main reactants in this process were and, while was used as the precipitator.

The nanometre scale HAP used in this study was prepared via a wet precipitation technique under the influence of ultrasonic irradiation. In this study two commercially available software packages Materials Studioand Endeavour ® 1.7b were used to model the crystal structure of a nanometre scale HAP powder from X-ray powder diffraction data. Due the close similarity between nanometer scale forms of HAP and the mineral phase found in the natural bone matrix, recent studies have focused on understanding the structure of HAP for its inclusion in a new generation of novel composites. Hydroxyapatite (HAP) is a biocompatible ceramic that is widely used in a number of biomedical applications and devices.
