摘要：
Single crystals of BaSrTiO3 have been grown by flux technique using KF as the flux. Morphology variation with Sr content and their growth conditions have also been investigated. Growth mechanism of the grown crystals 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 shows cubic at room temperature. Ferroelectric hysteresis loops have been traced for as-grown crystals.
