The X-ray powder diffraction technique has been used to test the formation of the compounds. Lattice parameters, space groups and basic structures of the compounds have been obtained from X-ray data. The dielectric constant has been measured as a function of frequency (100 Hz-10 kHz) and temperature (−180 to 200°C) to understand transition mechanism in these ferroelectric compounds.
