摘要
以二氧化钛(TiO2)和氢氧化钠(NaOH)为原料,经水热反应成功合成钛酸钠(Na2Ti3O7)晶体纤维。以合成的钛酸钠和五水硝酸铋(Bi(NO3)3·5H2O)为原料,NaOH为矿化剂,进行二次水热反应制备钛酸铋钠(Na0.5Bi0.5TiO3)粉体。通过X线衍射仪(XRD)和扫描电子显微镜(SEM)对反应制备的粉体进行物相分析,结果表明,通过二步水热反应,可制备出颗粒尺寸均匀的Na0.5Bi0.5TiO3聚集球。
Sodium titanate（Na2Ti3O7）crystal fibers were synthesized by hydrothermal method using TiO2 and NaOH as raw materials.Then using Na2Ti3O7 and Bi（NO3）3·5H2O as raw materials,NaOH as mineralizer,Na0.5Bi0.5TiO3 powders was prepared successfully with two-step hydrothermal.The phase composition and particle morphology of the as-prepared powders were characterized by X-ray diffraction（XRD）and scanning electron microscopy（SEM）.Analysis results indicated that the uniformity spherical agglomerates of Na0.5Bi0.5TiO3 were successfully prepared by two-step hydrothermal.
