A new nonlinear optical K2Al2B2O7 (KAB) crystal with a dimension of 2 mm th
ickness was grown by top-seeded solution growth (TSSG) using K2CO3-B2O3 flu
xes. The viscosity of the KAB-K2CO3-B2O3 and KAB-K2CO3B2O3-NaF (or LiCl and
KF) solutions were measured. The KAB platy growth habit, viscosity and sol
ution homogeneity are discussed. (C) 2000 Elsevier Science B.V. All rights
