eng	Thermal properties of MgO-Fe2O3-B2O3-P2O5 glasses	Magnesium borophosphate glasses doped with Fe2O3 were prepared and studied in the compositional series A: (40-x)MgO-xFe2O3-10B2O3-50P2O5 and B: 20MgO-20Fe2O3-yB2O3-(60-y)P2O5 within the concentration range of x (y) = 0-20 mol% Fe2O3 (B2O3). The structure of the glasses was studied by Raman spectroscopy, Mössbauer spectroscopy was used to monitor the changes in Fe2+/Fe3+ ratio. Differential thermal analysis, thermodilatometry and heating microscopy have been used to study thermal behaviour and stability of the glasses.	borofosforečnanová skla; MgO; Fe2O3; struktura; vlastnosti
