中文摘要：

纯二氧化钛(TiO_2 ) 粒子材料被 hydrolyzing 四氯化钛(TiCI_4 ) 准备。这些材料的微观结构被 X-raydiffraction (XRD ) 决定，加速的表面区域和 porosimetry 仪器(赌注) ，和传播电子显微镜学(TEM ) 。锻烧清楚地在不同温度下面获得的 TiO_2 材料在晶体结构类型，表面区域，毛孔尺寸，毛孔体积和谷物尺寸揭示了不同微观结构。在 TiO_2 材料和他们的 electrorheological 的微观结构之间的关系(嗯) 活动被调查。锐钛矿 titania 粒子比金红石 titania 粒子有更好的 ERperformance。非结晶的 TiO_2 材料更高显示嗯活动比水晶的 titania 材料。大毛孔体积能在改进粒子材料的 EReffect 是更有益的。

英文摘要：

Pure titanium dioxide （TiO2） particle materials were prepared by hydrolyzing titanium tetrachloride （TiCl4）. The microstructures of these materials were determined by X-ray diffraction （XRD）, accelerated surface area and porosimetry apparatus （BET）, and transmission electron microscopy （TEM）. The TiO2 materials obtained by calcinations under different temperatures distinctly revealed different microstructures in crystal structure type, surface area, pore size, pore volume and grain size. The relationship between the microstructure of the TiO2 materials and their electrorheological （ER） activity was investigated. Anatase titania particles have better ER performance than rutile titania particles. Amorphous TiO2 materials display higher ER activity than the crystalline titania materials. A large pore volume can be more advantageous in improving the ER effect of a particle material.
