【摘要】 本文首次报道了通过加入乙二醇单甲醇由工业硫酸钛液热水解制备ＴｉＯ２纳米微粉的工艺过程，并对其水解、锻烧条件进行了探讨．表征了ＴｉＯ２的晶型和颗粒度、分析了其纯度．结果表明，ＴｉＯ２为金红石型，颗粒大小为３５～４２ｎｍ，平均为３８ｎｍ，杂质含量小于０．１ｐｐｍ．更多还原

【Abstract】 The rutile Tio2 fine powders of the order of 35-42nm were prepared through the thermohydrolysis of the industrial titanium sulphate solution by adding the HOCH2CH2OCH3.The influcnccs of synthetic conditions for product were investigated. The TiO3 particles were well distributed and the content or foreign matter was less than 0.1 ppm.更多还原
