摘　　要：文中以TiCl_(4)为钛源,以Span80、OP-10和Tween40为乳化剂,并加入一定比例的水油,通过微乳液法制得纳米TiO_(2)前驱体,再通过二次煅烧技术制备纳米TiO_(2)粉体。研究表明,当乳化剂中Span80与Tween40质量配比为8︰2,其用量是10g时,水︰油质量比为1︰4。反应物TiCl_(4)的浓度为0.8 mol/L时制得的TiO2前驱体,在反应温度为500℃时,可获得性能良好的锐钛矿纳米TiO_(2),这为后期纳米TiO_(2)前驱体引入环保砖确定其最佳二次烧成温度奠定基础。In this study,TiCl_(4) as the titanium source,Using Span80,OP-10 and Tween 40 as emulsifiers,And add a certain percentage of water and oil,Nano TiO_(2) precursor by microemulsion,Then prepare nano TiO_(2) powder by secondary calcination technology,Studies show that when the mass ratio of Span80 and OP-10 in the emulsifier is 8︰2,The dosage is 10g;Water︰The oil mass ratio is 1︰4,The TiO_(2) precursor made at a concentration of the reactant TiCl_(4) of 0.8 mol/L,At a reaction temperature of 500℃,Good anatase nano-TiO_(2) can be obtained.This lays the foundation for the introduction of environmental brick to determine the optimal secondary firing temperature.
