Description

Full text: The sonochemistry study is used to understanding the effect of ultrasound in acoustic cavitation formation in liquids, resulting in the initiation or enhancement of the chemical activity in the solution. In this work Na2Ti3O7 nanopowder was synthesized by sonochemistry. Nanoparticles with mean diameter below of 20 nm, average crystallite size of 15 nm, were prepared through a simple sonochemical method. The structural and microstructural characterizations were studied by XRD, TGA-DTA and TEM. During the sonochemical irradiation, the raw material was broken and new phases were formed after ultrasonic irradiation. To explain the obtained results, it is supposed that edge sharing was favored during ultrasonic treatment, leading to formation of the Na2Ti3O7 nanoparticles. (author)
