Abstract

The effect of annealing temperatures on the formation of pure perovskite Na 0.5Bi 0.5TiO 3 (NBT) based ceramics prepared by sol gel method has been investigated. The NBT sol was prepared using NaCH 3COO, C 6H 9BiO 6 and Ti(C 4H 9) 4 with 2-methoxyethanol and glacial acetic acid were used as solvents. The BaTiO 3 sol was synthesized using C 4H 6BaO 4 and Ti(C 4H 9) 4 with acetic acid and ethanolamine were used as solvents. The (Na 0.5Bi 0.5) 0.96Ba 0.04TiO 3 (NBBT) sol was prepared by mixing appropriate amount of NBT and BaTiO 3 sols. Then NBT and NBBT sols were dried at 200°C for 24 h, ground and subsequently annealed at temperatures ranging from 440°C - 640°C for 5 min. Formation of NBT and NBBT ceramics was examined using XRD technique. X-ray diffractograms reveal that the NBT ceramic with rhombohedral structure starts to form at 540°C and complete crystallization is achieved at 620°C. Addition of 4vol% of BaTiO 3 sols drastically reduces the crystallization temperature of NBBT ceramic to 460°C and a pure single phase ceramic is achieved at 520°C. Despite retaining the same rhombohedral structure, the NBBT exhibits lattice parameters expansion indicating a successful Ba substitution which is also confirms by the absence of BaTiO 3 peaks in the diffractograms. Both ceramics exhibit great thermal stability with additional increment in annealing temperatures.
