Structural and Morphological Studies of Nanocrystalline Ceramic BaSr0.9Fe0.1TiO4

Full Text PDF

Abstract:

The development of lead-free piezoelectric materials have gained great attention for the consideration of environmental protection. Nanosized BaSr0.9Fe0.1TiO4, a lead free perovskite phase structured ceramic was prepared via a high-energy ball milling process through mechanically assisted synthesis. The sample was analyzed by X-ray Diffraction (XRD), SEM and EDX. The XRD results and XPERT-PRO software analysis confirmed the orthorhombic system of the sample. Scanning Electron Microscopy (SEM) analysis revealed that its crystallite size is in the nanometer range. The grain size was less than 100 nm and showed a strong tendency for agglomeration. It also confirmed with the calculated value from Debye Scherrer’s formula. EDX spectrum shows the elemental composition of the sample. Williamson-Hall Plot method was used to evaluate the size and lattice strain. The dislocation density and the morphology index of the sample were also calculated.
