Synthesis of Fe3O4 nanoparticles using controlled ammonia vapor diffusion under ultrasonic irradiation / Zunli Mo in Industrial & engineering chemistry research, Vol. 50 N° 6 (Mars 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 6 (Mars 2011) . - pp. 3534–3539 Titre : Synthesis of Fe3O4 nanoparticles using controlled ammonia vapor diffusion under ultrasonic irradiation Type de document : texte imprimé Auteurs : Zunli Mo, Auteur ; Chun Zhang, Auteur ; Ruibin Guo, Auteur Année de publication : 2011 Article en page(s) : pp. 3534–3539 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Ammonia  vapor  Ultrasonic  irradiation Résumé : Fe3O4 nanoparticles were synthesized for the first time via an ammonia vapor diffusion process under ultrasonic irradiation. The possible ultrasound mechanism and the process of ammonia diffusion and reaction has been deduced. Influences of experiment parameters such as reaction time, temperature on the morphology, and size of products were also investigated in detail. Morphology and magnetic properties of products were carefully studied by Fourier transform infrared spectra (FTIR), X-ray diffraction (XRD), Scanning electron microscopes (SEM), and vibrating sample magnetometer (VSM). The synthesized Fe3O4 nanoparticles possess superparamagnetic properties at room temperature, and the saturation magnetization is 70.5 emu/g.
