Structural Studies of BaTiO3 Ferroelectric Material Prepared by Green Chemistry (Sol-gel) Method

Abstract

Nano particle Barium Titanate (BT) is the first ferroelectric ceramics and a good nominee for a variety of applications from large family of Perovskite. In this study BaTiO₃ was synthesised by using Sol-gel (green chemistry) method. It is environmental friendly method and has a significant influence on the structure and properties of BT. XRD patterns were indexed on the basis of tetragonal-BaTiO₃ phase. The microstructure of the samples was investigated by using Scanning electron microscope (SEM). The grain size range was 90 nm for the dried gel powder for the powder calcined at . 1150°C. Infrared (IR) spectrum was recorded at room temperature. The absorption peak observed at 545 cm^-1 found to be BT characterization peak.
