Abstract
In the MgC6H6O7–H2O system, glass formation was detected for the first time, and the boundaries of the glass formation region were found to be in the range from 50 to 77 wt % MgC6H6O7. Glass-forming samples and the amorphous water-soluble compound MgC6H6O7 obtained by dehydration of the glass of the composition MgC6H6O7⋅3.5H2O at 40°C were studied by X-ray powder diffraction analysis, IR spectroscopy, and differential scanning calorimetry. The compositions of glass-forming samples resistant to crystallization were determined. The criterion for the crystallization resistance of glasses is the absence of crystallization during heating. The thermal curves of such glasses show only the event of Tg.
