【摘要】 文中以TiCl₄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TiO₂前驱体，再通过二次煅烧技术制备纳米TiO₂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TiCl₄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TiO₂，这为后期纳米TiO₂前驱体引入环保砖确定其最佳二次烧成温度奠定基础。更多还原

【Abstract】 In this study, TiCl₄ as the titanium source, Using Span80, OP-10 and Tween 40 as emulsifiers, And add a certain percentage of water and oil, Nano TiO₂ precursor by microemulsion, Then prepare nano TiO₂ 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 TiO₂ precursor made at a concentration of the reactant TiCl₄ of 0.8 mol/L, At a reaction temperature of 500℃, Good anatase nano-TiO₂ can be obtained. This lays the foundation for the introduction of environmental brick to determine the optimal secondary firing temperature.更多还原
