Characterization of Rod-like High-purity Fluorapatite Nanopowders Obtained by Sol-gel Method
نویسندگان
چکیده مقاله:
high purity fluorapatite (FA) with rod-like and spherical-like morphology was synthesized via sol-gel method. Chemical characterization of FA powders was done by XRD and FTIR analyses. Crystallite samples were calculated using Scherer method. Morphology of FA powders was investigated with TEM and SEM images. The results revealed that increasing the time of hydrolysis of phosphate sols significantly decreased the gelation time of FA sols. Also, mixing temperature of P and Ca sols affects the gelation time of samples and increasing pH decreases the gelation time of FA sols. Morphological and chemical characterization of samples showed that the FA powders have high purity and rod-like and spherical-like morphology.

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...

Este cunoscut că metoda sol gel este una din metodele neconvenţionale de obţinere a pulberilor ceramice. În studiul realizat s-a avut în vedere obţinerea şi caracterizarea de nanopulberi de Al2O3 prin metoda sol-gel, aceasta putand fi un potential material utilizat la realizarea de implanturi biocompatibile.[1,2,3,4] In vederea sintezei s-a pornit de la precursori de natură chimică diferită – a...
متن کاملStructural characterization of the V2O5/TiO2 system obtained by the sol–gel method
The influence of the vanadium load and calcination temperature on the structural characteristics of the V2O5/TiO2 system was studied by X-ray diffraction and X-ray absorption spectroscopy (XAS) techniques. Samples of the V2O5/TiO2 system were prepared by the sol–gel method under acid conditions and calcined at different temperatures. The rutile phase was found to predominate in pure TiO2 calcin...
