A new polymorph of Cd3B2O6 (β-Cd 3B2O6) has been grown through spontaneous crystallization with the flux system. β-Cd3B2O 6 crystallizes in triclinic space group P1 and features a three-dimensional Cd-O network composed of CdOn (n = 5, 6) distorted polyhedra and isolated planar BO3 groups. The phase transformation of Cd3B2O6 has been studied by the structure analysis and powder X-ray diffraction. TG-DSC measurement reveals the melting behavior and phase transformation temperature. Furthermore, the IR spectrum was measured. The detailed structure comparison between Cd3B 2O6 and other cadmium-containing borates, such as CdB 4O7, CdB2O4 and Cd2B 2O5 was also carried out.
