摘　　要：本文采用钛酸正丁酯作为钛源,乙醇作为反应溶剂,同时加入水解抑制剂盐酸来制备微、纳米级的二氧化钛,通过控制溶胶凝胶过程中的反应参数来考察不同粒径二氧化钛的合成方法,并通过激光粒度分析仪对产物的粒径进行了表征,最终确定制备符合条件粒径的二氧化钛粒子的最优配比和最佳条件。The titanium dioxide is prepared by the method of solgel. In this process, TiO2 is obtained from Ti（OBu）4 which carried by the solvent of alcoho. The hydrochloric acid was added into the process of hydrolyzationg as an inhibitor. The effects of the concentration of reagent, the kind of surface - active agents, reaction temperature, the adding quantity of water and acidity of solution, inhibitor dosage on the process are investigated. The particle size and particle size distributions of prepared powder is characterized by the laser particle size analyzer.
