以硝酸钡和钨酸钠为原料,采用十二烷基苯磺酸钠(SDBS)为表面活性剂,通过室温液相沉淀法制备出BaWO4纳米粒子.利用X射线粉朱衍射、扫描电子显微镜及透射电子显微镜对样品进行表征.结果表明,制得的BaWO4纳米粒子在表面活性剂SDBS的长时间诱导作用下可聚结成树枝状结构.
Barium tungstate nanoparticles are prepared via a simple deposition method, using barium nitrate and natrium tungstate as starting materials and dodecyl benzene sulfonic acid sodium salt(SDBS) as a surfactant. The samples are characterized by XRD,SEM and TEM. It is found that the dendrite assemblies of barium tungstate nanoparticles can be obtained by a simple deposition method with the induction of SDBS for a long time.
