- W928908323 abstract "以钛酸四丁酯为原料,采用水解-沉淀法制备TiO2纳米粉体,利用BET、XRD、IR、SEM和激光粒度分析仪等测试手段对制备TiO2粉体晶粒大小、粉体的粒度分布情况等进行了研究,并讨论原料配比,烧成温度,pH值与晶粒大小,物相组成等之间的关系。结果表明:在600°C到800°C之间,TiO2粉体由锐态矿转变为金红石,经800°C加热2h的物相主要为金红石,粉体呈类球形;pH为3.03,n(H2O):n[Ti(C4H9O)4]=30,400°C热处理2h后制备的TiO2粉末晶粒平均尺寸为80nm,粉体的平均粒度为580nm,比表面积为117.2631m2/g。" @default.
