Any other information on results incl. tables
During the melting tests of the three (3) cupro samples were heated in Al2O3crucible using nitrogen atmosphere.
Based on the TG/DSC measurements, the decomposition and melting of the cupro samples 09TT02932, 09TT02933 and 09TT05024, start at 630 °C, 748 °C and 1251°C.
09TT02932
The endothermic peak in the curve is at the temperature range 630 – 658 °C. It indicates melting or transformation.
09TT02933
The endothermic peaks in the curve are at the temperature ranges 748 – 944 °C and 969 – 1185°C. The mass of the sample starts to decrease at the temperature ~800 °C. These phenomena indicate that some components, obviously lead components, start to melt and evaporize.
09TT05024
The exothermic peaks are in the curve at the temperature ranges 1053 – 1104 °C and 1309 – 1352 °C. The mass of the sample starts to decrease at ~975 °C. These phenomena indicate reactions, which produces gas, with nitrogen. The endothermic peak in the curve is at the temperature ranges 1251 – 1290 °C. It indicates decomposition, evaporation and melting.
Applicant's summary and conclusion
- Executive summary:
Based on the TG/DSC measurements, the decomposition and melting of the cupro samples 09TT02932, 09TT02933 and 09TT05024 start at 630oC, 748 °C and 1251°C.
