Abstract

Nanocrystalline tin monoxide (SnO) has been synthesized through sonication-assisted precipitation technique at room temperature. The key in obtaining phase pure SnO at room temperature lies in exploiting high-power ultrasound (450W). The physical phenomenon responsible for the sonochemical process is acoustic cavitation. A mixed phase is formed on decreasing the ultrasonic power.-The heat generated during sonication does not explain the difference in phase formation under varying ultrasonic power as the difference in temperatures of the solutions during sonication under different power ratings was within 10-15 degrees C. SEM and XRD analysis were carried out for the investigation of powder morphology and crystalline structure of the material. (C) 2007 Published by Elsevier B.V.
