Synthesis and properties of dimagnesium hexaborate heptadecahydrate

Abstract A magnesium borate compound 2MgO·3B 2 O 3 ·17H 2 O has been synthesized and its structure studied by IR and Raman spectroscopy as well as by thermal analysis. The structural formula of this compound was Mg[B 3 O 3 (OH) 5 ]·6H 2 O. Its solubility in pure water at 25°C, refractive index, thermodynamic properties, and X-ray powder diffraction data are reported.
