Sol-gel synthesis and characterisation of nano- scale hydroxyapatite
Hydroxyapatite (HAp) forms the main mineral component of bone and teeth. This naturally occurring HAp is in the form of nano-metre sized crystallites of Ca10(PO4)6(OH)2 that contain a number of cation and anion impurities, for example CO3 , F, Na, Mg and Sr. Synthetic nano-sized HAp particles exhibit favourable biocompatibility and bioactivity and in order to better match the composition to nat...
متن کاملStoichiometric hydroxyapatite obtained by precipitation and sol gel processes
Se describen tres métodos para obtener hidroxiapatita (HA). La HA es una cerámica muy interesante por sus múltiples aplicaciones médicas. Los primeros dos métodos de precipitación parten de compuestos de calcio y fósforo, mientras que el tercer método es un proceso sol-gel que usa alcóxidos. Los productos fueron caracterizados y comparados entre sı́. Las diferencias observadas son importantes pa...
متن کاملSynthesis of zirconium carbide nanoparticles by sol-gel method and determination of powder characteristics
In this study, zirconium carbide nanoparticles were synthesized by the sol-gel method in the alcoholic system. The sol was prepared in a three-component alkoxide-water-alcohol system based on the chemical sol-gel process under acidic conditions and at pH = 5. Zirconium n-propoxide, furfuryl alcohol were used as raw materials. After the hydrolysis process and formation of the gel, the initial po...
متن کاملAntimicrobial Activity of Thin Solid Films of Silver Doped Hydroxyapatite Prepared by Sol-Gel Method
In this work, the preparation and characterization of silver doped hydroxyapatite thin films were reported and their antimicrobial activity was characterized. Silver doped hydroxyapatite (Ag:HAp) thin films coatings substrate was prepared on commercially pure Si disks by sol-gel method. The silver doped hydroxyapatite thin films were characterized by various techniques such as Scanning electron...
متن کاملSynthesis, characterization, of Fluorohydroxyapatite nanopowders by sol-gel processing
In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammon...
