Studies on sintering process of synthetic hydroxyapatite.
In this study the effect of sintering process in different temperatures on microstructure and morphological properties of sintered hydroxyapatite (HAp) was investigated. HAp powder was prepared by wet precipitation method from following reagents: Ca(OH)2 + H3PO4 in an alkaline conditions. Thermal analysis (TA), X-Ray diffraction method (XRD), FT-IR spectrometry (FT-IR) and scanning electron mic...
متن کاملSynthesis and Characterization of Hydroxyapatite Nanocrystals via Chemical Precipitation Technique
In this study, hydroxyapatite (HA) nanocrystals have been synthesized via chemical precipitation technique. Diammonium hydrogen phosphate and calcium nitrate 4-hydrate were used as starting materials and sodium hydroxide solution was used as the agent for pH adjustment. The powder sample was evaluated by techniques such as scanning electron microscope, transmission electron microscope, Fou...
متن کامل8YSZ sintering by flash sintering method and evaluation of process parameters
Flash sintering as a new sintering method for sintering of ceramic materials has been studied and effect of various parameter such as flash current density, time of flash and contact paste on properties of flash sintered 8YSZ samples has been investigated. Results showed it is possible to achieve high density in shorter time and lower temperature than conventional sintering methods. Samples cou...
متن کاملChemical analysis of silica doped hydroxyapatite biomaterials consolidated by a spark plasma sintering method.
Silica (SiO(2)) and the silicate-based biomaterials play an important role due to their in vitro and in vivo biological response. The present study synthesized a novel nano-structured amorphous silica doped hydroxyapatite (HA) via an aqueous precipitation route. HA was prepared with 0, 1, 3 and 5 wt% silica, which are comparable to the measured silicon content of natural bone. After spray dryin...
