Electrical characterization of hydroxyapatite-based bioceramics.
This paper studies the AC conductivity and permittivity of hydroxyapatite (HA)-based ceramics from 0.1 Hz-1 MHz at temperatures from room temperature to 1000 degrees C. HA-based ceramics were prepared either as dense ceramics or in porous form with interconnected porosity and were sintered in either air or water vapour. Samples were thermally cycled to examine the influence of water desorption ...
متن کاملNiobium-Doped Hydroxyapatite Bioceramics: Synthesis, Characterization and In Vitro Cytocompatibility
Doping calcium phosphates with ionic species can play an important role in biological responses promoting alkaline phosphatase activity, and, therefore inducing the generation of new bone. Thus, in this study, the synthesis of niobium-doped hydroxyapatite (Nb-HA) nanosize particles obtained by the precipitation process in aqueous media followed by thermal treatment is presented. The bioceramics...
متن کاملEstimation of the mean grain size of mechanically induced Hydroxyapatite based bioceramics via artificial neural network
This study focuses on the estimation of the mean grain size of mechanically induced Hydroxyapatite (HA) through the artificial neural network (ANN) model. The mean grain size of HA and HA based nanocomposites at different milling parameters were obtained from previous studies. The data were trained and tested by the neural network modeling. Accordingly, all data (55 sets) were based on the mecha...
متن کاملDeposition of Nano-Crystalline Fluor-hydroxyapatite Coatings on Titanium Substrates via Sol-Gel Method
In this investigation, fluor-hydroxyapatite (FHA) film was deposited on a titanium substrate by sol-gel method. Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol solutions were used respectively as P, F and Ca precursors. Typical apatite structures were obtained for all coatings after dipping and subsequent heat treatment at 550, 700 and 800 ºC, the coating layers were ...
متن کاملBiocompatibility and Biocorrosion of Hydroxyapatite-Coated Magnesium Plate: Animal Experiment
Magnesium (Mg) has the advantage of being resorbed in vivo, but its resorption rate is difficult to control. With uncontrolled resorption, Magnesium as a bone fixation material has minimal clinical value. During resorption not only is the strength rapidly weakened, but rapid formation of metabolite also occurs. In order to overcome these disadvantages, hydroxyapatite (HA) surface coating of pur...
