摘　　要：以Al_2(SO_4)_3·18H_2O、氨水为原料,通过沉淀法制备Al_2O_3前驱物。采用Hitach Su-1500带能谱的扫描电镜观测前驱物和煅烧产物形貌及其组成。研究表明,Al^(3+)的初始摩尔浓度对所制备Al_2O_3前驱物的颗粒形貌、前驱物的吸附性能、清洗过滤性能、颈部初烧结性能影响显著。In this paper, using aluminum sulfate（Al2（SO4）3 · 18H2O） and ammonia（NH3 · H2O） as raw materials, the Al2O3 precursor was prepared by chemical precipitation method. The morphology, size and composition of the Al2O3 precursor were explored by scanning electron microscopy（SEM） with energy dispersive spectrometer. The results showed： the Al^＋3 concentration affects remarkably the properties of the Al2O3 precursor including its morphology, adsorption, water filtering performance, and the initial sintering result of the neck growth.
