摘　　要：纳米Al_2O_3具有优越的性能而被广泛应用。实验探究在合适的pH值及分散剂配比下制备具有较优良过滤分离性能的Al_2O_3前驱物。通过实验可知,用硫酸铝来进行沉淀制备样品,pH值为7,分散剂配方为聚乙烯醇缩丁醛0.5%,磷酸三钠0.3%,十二烷基苯磺酸钠0.3%,OP0.1%时,所制备的Al_2O_3前驱物过滤分离性能最好。采用硫酸铝为铝源制备Al_2O_3前驱物比硝酸铝为铝源的前驱物过滤分离性能更佳。Nano alumina powder is widely used for a series advantage properties. In this paper the influence of different pH values and dispersant proportions on the properties of filtering separation was discussed. The experiment shows that when pH value is seven and the dispersing agents are that polyvinyl butyral of 0.5% and trisodium phosphate of 0.3%, SDBS of 0.3%, OP of 0.1%, the prepared aluminum precipitation precursor powder has the best properties of filtering separation. Using the aluminum sulfate as aluminum source. The properties of filtering separation of the prepared aluminum precipitation precursor is better with aluminum sulfate as aluminum source then aluminum nitrate.
