【摘要】 将二氧化钛溶于硫酸,过滤纯化,得到TiO2浓度为180~200g/L的钛液;将所述钛液缓慢加热至40~50℃后,加入到过量稀碱溶液中,在搅拌条件下,维持体系温度为40~50℃,调节酸度系数为0.27~0.3,进行水解反应,水解反应的终点pH控制在2.2~3.0,得到稳定性好,形貌均匀的高品质锐钛型晶种。晶种加量在1.5%~2%得到产品粒度适中,质量稳定。更多还原

【Abstract】 Firstly,Titania was dissolved in sulfuric acid,then filtering and purification,TiO2 concentration of titanium solution is180~200g/L.When the titanium liquid was slowly heated to 40~50 ℃,the excessive dilute alkali solution was added with stirring in temperature of 40~50 ℃,the acidity was adjusted in the range of 0.27~ 0.3.Finally,the hydrolysis reaction of pH in 2.2~3.0,the crystal has good stability,uniform morphology of high-quality anatase crystal.On the other hand,the influence of the quality with crystallizing amount and TiO2 concentration were also investigated.The experimental results exhibited that the amount of 1.5 %~2 % crystals is favorable for the production of stable production.更多还原
