| Abstract: | Nanoparticle of cerium borate with a size of about 50 nm was synthesized via sol-gel precipitation method under micro-emulsion by oleic acid,using Na2B4O7 and Ce(NO3)3 aqueous solution as raw materials,and the morphology and microstructure of as-prepared particles were characterized by means of scanning electron microscopy(SEM) equipped with an energy-dispersive X-ray spectrometer(EDS),X-ray diffraction(XRD),infrared spectroscopy(IR),and thermogravimetric analysis(TGA).Two methods to disperse the particles ... |
