Abstract
Fabrication and commercial application of nano-hydroxyapatite synthetic bioceramic compound is being implemented immensely worldwide in medicine, dentistry, and ceramic industries. In this experimental study, nano-hydroxyapatite has been prepared through the sol-gel method and doped with nano-silica, nano-alumina, and sodium zeolite. The main objective of this study is to improve the properties of nano-hydroxyapatite doped with nanoparticles of different metal oxides for load-bearing orthopaedic applications. The metal oxides have been doped in pure nano-hydroxyapatite by two different methods: physical attachment and chemical methods. After blending these metal oxides in nano-hydroxyapatite powder, comprehensive characterizations of compositional, structural, morphological, thermal, and mechanical properties have been determined through X-ray diffraction, Scanning Electron Microscope, Raman Spectroscopy, Thermogravimetric Analysis, respectively. The experimental outcomes revealed that all properties of the nano-hydroxyapatite material have been improved significantly with doping of metal oxides while nano-alumina was the most effective metal oxide.
