eng	Application of thermoanalytical methods to the study of glasses	Paper presents the application of Differential scanning calorimetry (DSC) and Thermodilatometry (TD) to understanding of the thermal behaviour of various phosphate and borophosphate glasses. From DSC curves the values of the glass transition temperature, Tg, and the values of crystallization temperature, Tc, were evaluated. From TD curves, the coefficient of thermal expansion, ?, the glass transition temperature, Tg, and the dilatometric softening temperature was determined. Beside basic thermal parameters, the thermal stability towards crystallization, the influence of glass composition on the nucleation mechanism, nucleation rate and critical cooling rate of the melt for glass formation was also studied. For the evaluation of thermal stability of glasses, ?T=Tc-Tg, criterion and the Hruby criterion [1] were applied.
