SnO2 Nanoparticle Synthesized by Ultrasonic-Assisted Process

Article Preview

Abstract:

SnO2 nanoparticles were synthesized by ultrasonic-assisted precipitation process using stannic chloride pentahydrate (SnCl4·5H2O) as a precursor. The stannic chloride aqueous solution was precipitated by ammonia under sonication. The as-synthesized precipitates were dried at 80 oC and then calcined at 400 oC for 2 h. The physical properties of nanoparticles with/without sonication were characterized by thermogravimetic and differential thermal analysis, X-ray diffraction, and transmission electron microscope. The results reveal that ultrasonic radiation has significant influence on phase transformation mechanism from Sn (OH)4 to SnO2, grain size and uniformity of SnO2 nanoparticles.
