Abstract Two series of glasses were synthesized by conventional rapid melt-quench method for different glass systems 55[(PbxBi1-x).TiO3]-44[2SiO2B2O3] and 65[(PbxBi1-x).TiO3]-34[2SiO2B2O3] doped with 1 mole percent of La2O3. X-ray diffraction study of synthesized glass sample shows amorphous nature while the glass ceramic sample revealed a cubic crystal structure due to devitrification of the glass as major crystalline phase of bismuth titanium oxide. X-ray absorption spectroscopy measurements in transmission mode were carried out and confirm the maximum value of absorption coefficient, 3.05 at energy 13450 eV for lead free glass ceramic sample. Scanning electron microscopy and contact angle measurements were also performed to explain the surface morphology. Energy dispersive X-ray analysis confirmed the presence of grains of bismuth titanium oxide and its elemental analysis with O, Ti, Si, Bi nanoparticles. The inclusions of La2O3 results in development of well interconnected crystallites were formed as major phase of bismuth titanium oxide.

摘要 针对不同的玻璃体系，采用常规快速熔融淬火法合成了55[(PbxBi1-x).TiO3]-44[2SiO2B2O3]和65[(PbxBi1-x).TiO3]-34[2SiO2B2O3]掺杂的两个系列玻璃。含有 1 摩尔百分比的 La2O3。合成玻璃样品的 X 射线衍射研究显示出无定形性质，而玻璃陶瓷样品显示立方晶体结构，这是由于作为钛酸铋主要结晶相的玻璃的失透。在透射模式下进行 X 射线吸收光谱测量并确认无铅玻璃陶瓷样品在能量 13450 eV 下吸收系数的最大值为 3.05。还进行了扫描电子显微镜和接触角测量以解释表面形态。能量色散 X 射线分析证实了铋钛氧化物晶粒的存在及其与 O、Ti、Si、Bi 纳米颗粒的元素分析。La2O3 的夹杂物导致良好互连的微晶的发展，形成作为铋钛氧化物的主要相。
