Reproducibility of Aluminum Alloy
Two different samples of aluminium alloy (Al-Mg-Si) were measured with the DSC 404 F3 Pegasus® during heating and cooling. Melting and also solidification of the alloy is clearly visible in the measurement results. The differences between the two different samples, however, are small. The characteristic temperatures (onset, peak) agree all within 0.3 K. The differences in the peak areas are less than 1% for both heating and cooling. The good agreement between the two measurement results demonstrates the excellent capability and reproducibility of the DSC 404 F3 Pegasus®.

Phosphate glass
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.
