Iranian materials engineers increased flexural strength and toughness of hydroxyapatite pieces by using oxide nanoparticles compatible with the body.

Metal Nano-Oxides Improve Properties of Hydroxyapatite Synthesized through Biocompatible Method

Tehran, Iran | Posted on February 17th, 2014

The synthesis of the base of nanocomposites was similar to the mechanism that takes place inside the body in this research. The aim of the research was in fact to produce nanocomposite powder and nanocomposite objects based on hydroxyapatite that were strengthened with aluminum and titanium oxide nanoparticles.

The nanoparticles improve mechanical properties of the produced objects, including their flexural strength and toughness, and cause hydroxyapatite to decompose at higher temperatures. It enables the sintering of hydroxyapatite at higher temperatures to obtain higher density and strength.

Among the most important achievements of the plan, mention can be made of significant increase in flexural strength up to about 27% in the sample modified with titania, and about 40% in the sample modified with alumina. The toughness of these pieces increased 100% in comparison with the pure nanostructure hydroxyapatite sample.

Taking into account the importance of hydroxyapatite as the main character of bone materials, the research can have a good foresight into medical engineering and biomaterials applications. Moreover, new applications have been drawn for hydroxyapatite nanopowder as catalyst and permeable and semi-permeable membranes, and the product can be used in such industries too.

Results of the research have been published in Ceramics International, vol. 39, issue 3, April 2013, pp. 2197-2206.
