Ovchinnikov, S. G.; Rudenko, V. V. JOURNAL OF CRYSTAL GROWTH, 455 55-59; Doi: 10.1016/j.jcrysgro.2016.09.047 DEC 1 2016

The temperatures for saturation of the MBO3 (M=Fe, Ga, In, Sc, Lu) compounds in the M2O3–B2O3– (70 PbO–30 PbF2, wt%) solvents are determined. The growth rates of FeBO3 and GaBO3 crystal faces as functions of the flux supercooling are obtained. It is demonstrated that the bulk FeBO3 and GaBO3 crystals can be grown in a narrow flux supercooling range using a controlled seeding technique. The MBO3 (M=In, Sc, Lu) crystals in the form of (111) plates are synthesized by spontaneous crystallization.
