摘要A new magnesium borate mineral, Mg[B6O7(OH)(6)]center dot 5H(2)O was synthesized via dilution method from boron-bearing Na-K-Mg-Cl-SO4 salt lakes. The crystal structure of the new phase was solved and refined using Xray powder diffraction data and characterized with FTIR and Raman. Its asymmetric unit consists of one Mg atom, one B6O7(OH)(6) cluster and five H2O molecules. The Mg atom is 6-coordinated with six O atoms to faun a MgO6 octahedron. Thermal gravimetry (TG/DSC) was used to investigate the thermal behavior of the new compound. During the high temperature decomposition process the dehydrated product MgB4O7 formed. The optical absorption characteristic of this new mineral was investigated by UV-Vis spectrometer and its energy gap E-g is about 4.44 eV.
