| 摘 要： | 以五氧化二铌(Nb2O5)和氧化镁(MgO)为原料,柠檬酸作配位剂,采用静电纺丝结合溶胶-凝胶法制备了铌酸镁(MgNb2O6)陶瓷纤维。在本合成体系中,高质量Nb5+溶液的获得是形成MgNb2O6前驱体溶胶的关键步骤。通过TGA,FTIR,XRD,TEM以及SEM技术对纤维的形貌,微观结构以及组成进行了表征。结果表明,900℃烧结以后得到的MgNb2O6纤维长度约为10 cm,具有中空结构,壁厚约为800 nm。

| Abstract: | MgNb2O6 ceramic fibers were synthesized using niobium oxide and magnesium oxide as starting materials by the electrospinning with sol-gel process.Citric acid was used as the chelating reagent to coordinate to the metal ions.The key step to the formation of MgNb2O6 precursor sols is to obtain a high quality solution of Nb5+.The morphology,structure,and composition of MgNb2O6 fibers were characterized by TGA,FTIR,XRD,TEM and SEM techniques.The results show that MgNb22O6 fibers calcined at 900 °C with length in the order of 10 cm have the hollow structure and are composed of nanoparticles (particle size＜100 nm) and the thickness of the wall is no more than 800 nm. |
