对在超声场作用下采用氨水中和氯氧锑(Sb4O5Cl2)制备超细立方晶型Sb2O3的工艺过程和条件进行了研究. 结果表明, 在超声场作用下制得的Sb2O3为立方晶型, 当超声功率为100W, 超声时间30min, 温度为20℃时, Sb2O3的平均粒径为0.777μm, 其分散性较好. 通过XRD、SEM和激光粒度仪等测试手段, 探讨了超声功率、超声时间、氯氧锑与蒸馏水的调浆液固比和温度等条件对Sb2O3晶型和颗粒粒径的影响.
The preparation of ultrafine cubic Sb2O3 was studied by using oxychloride (Sb4O5Cl2) neutralized with ammonia under ultrasonic field. The results show that Sb2O3 obtained in the process is cubic crystalline and well-dispersed, which has an average particle size of 0.777μm when the ultrasonic power is 100W, the ultrasonic time is 30min, and the temperature is 20℃. The effects of ultrasonic power, time, ratios of distilled water to oxychloride, and temperature on the crystal structure and particle size of the Sb2O3 formed were investigated by means of XRD, SEM and laser sizer.
