09TT02771
The endothermic peaks in the curve are at the temperature ranges 643 – 774 °C, 905 – 924°C and 1029 – 1073 °C. The mass of the sample starts to decrease slowly at the temperature range ~200 °C and decreasing becomes faster at ~800 °C. This indicates evaporation or decomposition of some components. The peak at the temperature range 1029 – 1073 °C indicates melting.
09TT02773
The endothermic peaks in the curve are at the temperature ranges 652 – 830 °C and 1036 – 1150 °C. Because the mass of sample starts to decrease later than the first peak is, this indicate, that some components melt already at the temperature 652 – 830 °C. Evaporation and decomposition starts above 750 °C.
Applicant's summary and conclusion
- Conclusions:
- Based on the TG/DSC measurements, the melting of the black copper samples 09TT02771 and 09TT02773 start at 643 °C and 652 °C.
