中文摘要：

以熔盐法合成的片状SrTiO3，Bi4Ti3O12为种晶，分别采用模晶生长法（TGG）和反应模晶生长发（RTGG）制备了具有〈001〉取向的0．94（Na1/2Bi1／2）TiO3-0．06BaTiO3（NBT-6BT）织构陶瓷。研究了不同种晶选择、流延和热处理工艺参数对陶瓷织构化程度、显微结构和压电性能的影响。结果表明，RTGG制备的织构陶瓷比TGG的在结构和性能等方面都具有优势，且用该方法以Bi4Ti3O12为种晶，制备出了高密度（f≥96％）、高织构度（F≈95％）、高性能（d33≈241pC／N）的NBT-6BT无铅压电陶瓷。

英文摘要：

The 〈001〉 fiber-textured （Na1/2Bi1/2）TiO3-6BaTiO3 （NBT-6BT） ceramics were fabricated by （reactive） templated grain growth method, using plate-like SrTiO3 and Bi4Ti3O12 particles as the templates prepared by a molten salt method. The effect of template selection process parameters on texture development, microstructure evolvement and piezoelectric properties was studied. High Lotgering factor （≈ 95%） and high density （≥96% theoretic density） textured NBT-6BT lead-free piezoelectric ceramics using Bi4Ti3O12 as templates were prepared and exhibited good piezoelectric performance with piezoelectric coefficient d33=241 pC/N.
