- Abstract
Various glass samples were prepared in the system [(PbSr)O · TiO]-[2SiO · BO]-[KO]-[BaO]-[NbO] (0.5 ≤ x ≤ 1) by melt quench method. Donor dopant NbO has been found to play an important role in the crystallization of the parent glasses. X-ray diffraction studies indicated that perovskite lead titanate (PT) or perovskite (Pb, Sr)TiO (PST) crystallize as a major phase followed by secondary phases of PbTiO, PbBO and TiO (Rutile). Scanning electron microscopy (SEM) shows the uniform and well-interconnected morphology of the crystallites. Energy dispersive X-ray analysis (EDAX) confirms the formation of perovskite PT/PST solid solution as major phase.
