Abstract

The effects of Lead oxide (as solvent) content in the perovskite phase formation in spontaneous growth of PZN single crystal have been studied. In spite of adopting columbite route, 50 wt% of solvent leads to the growth of undesirable pyrochlore phase. With the increase of solvent content, the probability of formation of perovskite phase was found to increase. Growth run performed with PZN/PbO weight ratio 35:65 resulted the growth of crystals with > 98% perovskite phase present in it. With the help of oscillating thermal profile PZN single crystal was grown of the size 10× 10× 8 mm 3 .
