【摘要】 实验以TiCl4为原料,采用低温液相水解法制备了纳米TiO2粉体,着重研究了Ti4+的浓度和添加聚乙烯吡咯烷酮(Polyvinylpyrrolidone,PVP)对产物的晶相、颗粒大小和表面形貌的影响．使用XRD,TEM,SEM,激光粒度测试仪对样品进行了表征．更多还原

【Abstract】 Nanometer TiO2 powder has been prepared by lower temperature hydrolytic precipitation method using TiCl4. The effects of Ti4+ ion concentration and PVP addition on TiO2 powder crystal structure, particle size, size distribution and morphology were investigated. The nanometer TiO2 powders obtained were analyzed by XRD, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and laser zeta sizer (LZS).更多还原
