Synthesis of Rutile Tatania by Heterogeneous Nucleation Methods

YANG Shao Feng, ZHAO Chun, SONG Li Zhu*, ZHAO Jing Zhe WANG Zi Chen, XU Hui Fang, LI Bo Fu (Department of Chemistry, Jilin University, Changchun 130023, China)  
Rutile tatania powders were synthesized in aqueous solutions, avoiding the appearance of TiO 2 in anatase form, by heterogeneous nucleation methods with SnCl 2·2H 2O(method A) and SnCl 4·5H 2O(method B) as the raw materials respectively. The effects of nuclei and peptizing conditions on the structures of products were investigated. The mechanisms of nucleation were studied by comparing the results of the two different raw materials. The content of SnO 2 in the samples with a full rutile structure was 10% and 8%(molar fraction) for the two methods respectively.
