Abstract
In the present study, three different compositions of phosphate glass were studied by differential scanning calorimetry. A family of heat flow curves were analyzed to evaluate the glass transition activation energy. The experiment successfully determined the glass transition state activation energy for lead phosphate, 4.35 eV, and calcium phosphate 4.82 eV, and calcium fluoride phosphate 5.99 eV. The results support the theory that the breaking of the P-O bond plays an important role in the mechanism of the glass transition.
