Synthesis, Crystal Structures and Characterization of Ba5LiTiNb9O30
【Abstract】 A new niobate compound with the chemical composition of Ba5LiTiNb9O30 was synthesized by doping Li+ into the system BaO-TiO2-Nb2O5 in conventional solid state reaction method. The crystalline structure was determined by X-ray diffraction analysis (XRD). The results showed that crystal structure of Ba5LiTiNb9O30 belongs to tetrago-nal tungsten bronze structure with space group P4bm and its unit cell parameters: a=b=1.2512(2) nm, c=0.4008(5) nm. The microstructure of reaction products was observed by scanning electron microscopy (SEM).
