- Melting / freezing pt.:
- > 650 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 650 °C
- Remarks on result:
- other: No melting point was determined prior to the decomposition and/or sublimation of the test item , starting at approx. 650°C
- Conclusions:
- No melting point was determined prior to the decomposition and/or sublimation of the test item, starting at approx. 650°C.
- Executive summary:
The DSC measurement was combined with a thermogravimetric (TG) measurement according to OECD Test Guideline 102 [adopted on 27 July 1995] and EU test method A.1 “Melting/freezing temperature“, Council Regulation (EC) No 440/2008 of 30 May 2008.
The heat flow curve shows a very small endothermic peak at 228°C (226°C extrapolated onset), which corresponds to the melting point of tin (230°C). Upon further heating a larger endothermic effect is registered starting at 747°C, with a peak maximum temperature at 858°C. Simultaneously to the endothermic heat flow, however, a significant mass loss is observed. After cooling down, the sample holder, the reference crucible as well as the sample crucible are covered with a grey precipitation (sample crucible inside and outside). Therefore the endothermic peak cannot be related to melting, but to decomposition and/or sublimation.
