Phosphate Glass Powder — Glass Transition, Structural Change, Specific Heat

A fine grained phosphate glass powder was measured between room temperature and 1100°C. Typical for such glass types, the glass transition was measured at 483°C (midpoint). At 632°C, an exothermal effect was obtained. This effect is most probably caused by structural changes in the material and/or agglomeration of the powder particles above the softening point. The large surface of the powder is reduced causing a slight energy release. The energy release superimposes the true specific heat values between 600°C and 900°C.
