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.
