Abstract

Dislocations in LiB3O5(LBO) single crystal were investigated by white-beam synchrotron radiation topography(WBSRT). The WBSRT revealed that the grown-in dislocations are mainly pure screw or edge types with the Burgers vectors in the low index directions on (010) lattice plane. Based on the structure analysis, the formation cause of dislocations can be interpreted in terms of the loose packing of B-O rings and the low density of Li+ on (010) lattice plane.
