Vi. Chani et al., Segregation and uniformity of K3Li2(Ta,Nb)(5)O-15 fiber crystals grown by micro-pulling-down method, J CRYST GR, 194(3-4), 1998, pp. 374-378
Single crystal fibers of K3Li2(Ta,Nb)(5)O-15 (KLTN) have been grown using m
icro-pulling-down technique. Crystals were produced from the melts containi
ng 0-10 mol% of Ta2O5. Composition characterization was made by electron-pr
obe microanalysis. Fast growth rates (about 0.5 mm/min) were found allowed
preparation of macro defect free KLTN crystals with constant Ta:Nb cation r
atio and segregation coefficients of Ta and Nb close to unity. (C) 1998 EIs
