摘　　要：采用改进的水热合成法制备了纳米二氧化钛晶种,通过XRD、TEM和EDS等对其结构进行表征,表明该材料为纯相锐钛型晶种。此外,选择常压水解条件,研究晶种加入量对水解产品的影响。结果表明在1.5%~2%的晶种量有利于生产合格的稳定产品。The nano TiO_2 crystal material was synthesized by a modified hydrothermal method, which was also characterized by XRD, TEM and EDS. The results showed that all powders were the single anatase titania and their primary particle size was about 12.8 nm. On the other hand, the influence of the quality with crystallizing amount was also investigated. The experimental results exhibited that the amount of 1.5 %~2 % crystals is favorable for the production of stable production.
