Synthesis of Hydroxyapatite Bio-Ceramic Powder by Hydrothermal Method
Hydroxyapatite bio-ceramic powder was synthesized using waste eggshells as calcium source by a straight forward thermal method. The process is carried out at high temperature. Different calcium phosphate phases were obtained just by changing the thermal treatment. HAp is the only apatite present in the reaction products, along with minute fractions of other calcium compounds. The final product ...
متن کاملSurfactant-assisted preparation of fluoride-substituted hydroxyapatite nanorods
Fluoride-substituted hydroxyapatite (FHAp) nanorods have been successfully prepared by adding Tween80. As compared to the spheroidal morphology without any surfactant, the FHAp nanorods prepared with Tween80 were elongated along the c-axis. The reason was attributable to the enlarged difference between the growth rates of crystal surfaces due to the adsorption of Tween80. The effects of the pH ...
متن کاملPreparation and characterization of hydroxyapatite-coated iron oxide particles by spray-drying technique.
Magnetic particles of iron oxide have been increasingly used in medical diagnosis by magnetic resonance imaging and in cancer therapies involving targeted drug delivery and magnetic hyperthermia. In this study we report the preparation and characterization of iron oxide particles coated with bioceramic hydroxyapatite by spray-drying. The iron oxide magnetic particles (IOMP) were coated with hyd...
متن کاملPreparation and Characterization of Nanostructure Akermanite Powder by Mechanical Activation Method
Objective(s): So far, extensive research has been conducted on the preparation and characterization of nano ceramics based on Ca-Si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (MA). The aim of this study was the preparation of akermanite nano powder by mechanical activ...
متن کاملDual functional selenium-substituted hydroxyapatite.
Hydroxyapatite (HA) doped with trace elements has attracted much attention recently owing to its excellent biological functions. Herein, we use a facile co-precipitation method to incorporate selenium into HA by adding sodium selenite during synthesis. The obtained selenium-substituted HA products are needle-like nanoparticles which have size and crystallinity that are similar to those of the ...
