摘要
介绍了纳米二氧化钛(TiO2)的生产现状和几种主要制备方法,通过对几种制备方法的比较,提出了以硫酸法TiO2生产的中间产物硫酸氧钛(TiOSO4)或偏钛酸(H2TiO3)为原料,采用均匀沉淀法制备纳米TiO2的工艺路线。研究了相关的工艺过程及反应条件、水解产物的洗涤和金红石型纳米TiO2的煅烧,对存在的问题和今后的研究方向进行了讨论。
The present manufacture situation of nano - Ti duced. Through comparison nano - TiO2by homogeneous of several manufacture methods precipitation method, based on semifinished products during the production of TiO2 process, reaction condition, washing hydrolysate and cal 02 and several manufacture methods were intro- , the technological route of the manufacture of TiOSO4 or H2TiO3 as raw materials which are sulfuric and the existing problems and future development were discussed method, was presented. The techical futile type nano -TiO2 were investigated,
