摘要: 以硝酸铝和碳酸氢铵为原料，采用超声波辅助沉淀法制备Al2O3粉体，利用XRD和SEM对所制备的粉体的物相和形貌进行表征，考察了干燥方式和水浴温度对粉体制备的影响。结果表明真空冷冻干燥较传统鼓风干燥制得的氧化铝粉体分散性更好，粒径更均匀；氧化铝粉体的粒径随着反应温度的升高而增大，适宜的水浴温度为25℃；利用超声波辅助沉淀法制得了粒径分布窄、分散性好的纳米氧化铝粉体。
Abstract: Using aluminum nitrate and ammonium bicarbonate as starting materials, nano-alumina powders were prepared by ultrasonic-assisted precipitation method. The influence of drying method and bath temperature on the synthesized powders was investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the better dispersion and more uniform powders were prepared by vacuum freeze drying than the traditional air blast drying. The particle size of alumina powder increases with the increase of bath reaction temperature, and the suitable reaction temperature is 25˚C. Nano-alumina powders with narrow particle size distribution and good dispersion were prepared by ultrasonic-assisted precipitation method.
