| Abstract: | The defects such as inclusion,splitting,dislocation and dendrite in the PbxLa1-x(Zry Tiz Sn1-y-z)O3(PLZST) single crystal grown from PbO-PbF2 flux by the slow cooling self-seeding technique were discussed in this paper.The forming mechanism of these defects were analyzed and some measures to eliminate the defects were proposed. |
