PREPARATION, MORPHOLOGY AND X-RAY-DIFFRACTION STUDIES ON BARIUM STRONTIUM-TITANATE SINGLE-CRYSTALS

Single crystals of BaSrTiO3 have been grown by flux technique using KF as the flux. Morphology variation with Sr content and their growth co nditions have also been investigated. Growth mechanism of the grown cr ystals is discussed with the help of micromorphologies observed on the habit faces. X-ray diffraction studies on the crushed crystals with 5 mole % to 20 mole % show tetragonal structure and for 30 mole % it sh ows cubic at room temperature. Ferroelectric hysteresis loops have bee n traced for as-grown crystals.
