perovskite been synthesized

employing co-precipitation technique. X-Ray Diffraction

(XRD) and Fourier-transform Infrared spectroscopy (FTIR)

analysis were used to explore the structural features and

calculate lattice parameter values for all the compositions

(as prepared, sintered at 200, 400, 600, 800 and 1000 0C for

3h). Formation of nanoparticles was revealed by transmission

electronmicroscopy (TEM). The elemental analysis as obtained

by EDAX is in close agreement with the expected composition

from the stoichiometry of reactant solutions used. Increasing

sintering temperature enhances theperovskite structure to800

0C. Theperovskite structure is distortedabove this temperature.

Crystallite size was determined by three method Scherrer,

Williamson Hall, and Warren Averbach to be in ranging from

33 to 86nm.
