纳米晶金红石TiO2结晶形态

Effect of Heat Treatment on the Crystal Morphology of Nanoscale Rutile TiO 2 Powder

摘要:

ＴｉＣｌ３氧化烧结制备了纳米晶金结石ＴｉＯ２。通过Ｘ射线衍射（ＸＲＤ）分析其物相，采用透射电镜（ＴＥＭ）详细观察和分析了不同温度烧结的金红石ＴｉＯ２纳米晶的形态结构。研究表明，纳米晶金红石与常规金红石有很大的区别，前者为｛１１０｝面组成的单形，后者却为聚形。

Abstract:

A nanoscale rutile TiO 2 powder has been prepared from TiCl 3. The crystal morphology of TiO 2 powder sintered at various temperatures were studied in detail using XRD and TEM. The results show that there are many morphological differences between nanoscale rutile and common rutile, the former is simplex.
