Nanocrystalline Hydroxyapatite Ceramics Prepared by Hydrolysis in Polyol Medium, Microstructure and Mechanical Properties after Spark Plasma Sintering
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2014, Vol 6, Issue 3
Abstract
This Letter describes a new approach for the synthesis of hydroxyapatite (HA) nanoparticles by polyol process has been successfully conducted by spark plasma sintering process, resulting in a dense hydroxyapatite compacts. Besides, the sintering behaviour of hydroxyapatite powders at different temperatures ranging from 800°C to 950°C at 50 MPa was studied. The microstructure, Vickers microhardness, fracture toughness and density are described. The suitable sintering condition under the pressure of 50 MPa is 900°C for 5 min. A maximum value of the density was reached at around 900°C, and then decreased with further increase in the temperature due to the decomposition of hydroxyapatite into β-tricalcium phosphates.
