YAN Zhe-hua, DAI Li, SUN Jin, et al. Segregation Coefficient of Zr: Fe: LiNbO3 Crystals Grown by TSSG Method[J]. 2016, 21(4): 80-82.DOI: 10.15938/j.jhust.2016.04.015.
Zr: Fe : LiNbO3 crystals with various Li/Nb ratios ( Li/Nb = 0. 94
1. 05
1. 20
1. 38 ) have been grown by Top Seeded Solution Growth method. The segregation coefficient of the Zr4 + and Fe3+ were measured. It can be derived from measurement made that the segregation coefficient of the Zr4+o f Zr:Fe:LiNbO3 crystal decreased with increased Li/Nb ratios and its tend to 1. And that with the increase of Li/Nb mole ratios in the melts
the increases Li/Nb mole ratios in the crystals. The experimental results were analyzed based on the Li-va- cancy defect model.
