Preparation of ultrafine cubic Sb2O3 crystals under ultrasonic

The processes and conditions for ultrasonic preparation of cubic Sb2O3 crystals under ultrasonic by neutralizing Sb4O5Cl2 with ammonium hydroxide were researched. The effects of ultrasonic power, time and temperature as well as ratio of Sb4O5Cl2 to water on the crystal form and particle size of Sb2O3 were investigated by X-ray diffraction, scanning electron microscopy and laser particle size analyzer. Cubic Sb2O3 crystals were prepared by being sonicated at 100 W and 20 °C for 30 min. The particles were cubic-like, with the average size of 0.777 μm.
