We have studied and optimized conditions for spontaneous flux growth of TbCr3(BO3)4 crystals.
Phase relations in the pseudoternary system TbCr3(BO3)4–K2Mo3O10–B2O3 have been studied in the temperature
range 900–1130°C and the single-phase terbium chromium borate crystallization field has been
mapped out. It has been shown that increasing the TbCr3(BO3)4 content of the starting high-temperature
solution leads to a rhombohedral-to-monoclinic phase transition. Using K2Mo3O10-based high-temperature
solutions, we have grown single-phase TbCr3(BO3)4 single crystals or crystals in which the rhombohedral
phase (sp. gr. R32) significantly prevails over the monoclinic phase (sp. gr. C2/c). The grown crystals have
been characterized by X-ray diffraction techniques, IR spectroscopy, and magnetic measurements.
