摘　　要：在十一烯酸和十二胺作表面活性剂、正辛烷为油形成的油包水(W/O)型微乳液体系中,通过调节体系的组成,使Na2WO4和BaC l2发生反应,分别制得了丝状、棒状和空心球状的BaWO4纳米粒子。利用XRD、TEM和HRTEM测试技术对相关产物进行了分析表征。初步研究了BaWO4纳米丝和空心球状BaWO4粒子的Ram an特性。BaWO4 nanoparticles of wire, rod, and hollow spherical shapes were prepared in different micmemulsion systems with octane as the oil, and undecylenic acid and/or dodecylamine as the surfactants. The powder was characterized by XRD, TEM and HRTEM. The Raman spectra of the BaWO4 nanowires-and hollow BaWO4 spherical particles were also presented. This method may be extended to prepare novel nano- structures of other tungstates.
