When the molar fraction of SnO2 is 83%, the main component of the coating isO2 solid solution with rutile structure. When the molar fraction of SnO2 is 44%, the main components of coating are theO2 solid solution with rutile structure andO2 solid solution with fluorite structure. When the molar fraction of SnO2 is 17%, the main component of the coating isO2 solid solution with fluorite structure. Annealed at higher temperature than 450 ℃, CeO2 is found in the coating containing 83%Sn, and there is not SnO2 in the coating containing 83%Ce, which suggests that fluoriteO2 has higher thermal stability than rutileO2. When the molar fraction of SnO2 increases, the dispensability of the coatings is improved greatly.

结果表明：通过控制制备条件可获得具有纳米结构的钛阳极涂层；当Sn的摩尔分数为83%时，涂层主要为金红石相的O2固溶体；当Sn的摩尔分数为44%时，涂层中金红石相O2固溶体和萤石结构的O2固溶体共存；当Sn的摩尔分数为17%时，涂层由萤石结构的O2固溶体组成；高于450 ℃退火时，含83%Sn的涂层中出现CeO2相，而在含83%Ce的涂层中没有出现SnO2相，表明在相同的溶质浓度下，萤石结构的O2固溶体比锡基金红石相O2固溶体具有更好的热稳定性；而涂层中的SnO2具有明显改善涂层分散性的作用。

In other words,under the same reaction conditions,the larger the particle size of theprecursor mixed powder,the higher the temperature at which Zn_2TiO_4 starts to appear.There are structure similarity phenomena in ZnO-TiO_2 system,i.e.,the connectionmanner of TiO6 octahedra in the structure of ZnTiO_3 is similar with the one of rutile,andthe connection manner of TiO6 octahedra in the structure of Zn_2TiO_4 and Zn_2Ti_3O_8 issimilar with the one of anatase.

ZnO-TiO_2系统中存在一种类构现象，即：ZnTiO_3结构中的氧八面体的连接方式和金红石TiO_2的相似，而Zn_2TiO_4和Zn_2Ti_3O_8结构中的氧八面体的连接方式则和锐钛矿TiO_2的相似，并由此衍生出一个类构效应理论，即：ZnO和金红石TiO_2的反应产物中不应该出现Zn_2TiO_4和Zn_2Ti_3O_8当然，反应温度应低于ZnTiO_3的起始分解温度。

On the other hand, the enrichments of Pb and Sr at the rim of the interstitial rutiles suggest influence of subsequent fluids on the compositions of rutiles, which could have affected Zr of the rutiles as well This study provides the evidence for the Zr diffusion at a high temperature and fluid activity that could have contributed to the lower temperatures (598-827℃) recorded by Zr-in-rutile for the eclogites from the Dabie-Sulu UHP terrane.
