Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 16th February 2018 to 21st February 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- unsuitable test system
- Justification for type of information:
- Melting point was already determined to be greater than 1000 °C based on testing via thermogravimetric analysis, which has a maximum measurement temperature of 1000 °C. Therefore, an attempt was made to melt the substance in a furnace using temperatures of up to 1050 °C.
- Qualifier:
- according to guideline
- Guideline:
- other: Internal method
- Version / remarks:
- attempt was made to melt the substance in a furnace using temperatures of up to 1050 °C
- Principles of method if other than guideline:
- The material was heated in a furnace until signs of melting were observed.
Three seperate firings were attempted, one at 1000 °C, one at 1040 °C and one at 1050 °C. - GLP compliance:
- no
- Type of method:
- other: Heating within furnace with observation of melting.
- Specific details on test material used for the study:
- Batch number B1759
- Key result
- Melting / freezing pt.:
- >= 1 040 - <= 1 050 °C
- Conclusions:
- Melting point had previously been determined to be greater than 1000 °C based on testing via thermogravimetric analysis, the equipment for which has a maximum measurement temperature of 1000 °C. Therefore, an attempt was made to melt the substance in a furnace using temperatures of up to 1050 °C.
At 1040 °C no sign of melting was observed on removal from the furnace, whereas at 1050 °C, the substance has melted. Therefore, melting point is determined to be somewhere between 1040 and 1050 °C. - Executive summary:
Melting point had previously been determined to be greater than 1000 °C based on testing via thermogravimetric analysis, the equipment for which has a maximum measurement temperature of 1000 °C. Therefore, an attempt was made to melt the substance in a furnace using temperatures of up to 1050 °C.
At 1040 °C no sign of melting was observed on removal from the furnace, whereas at 1050 °C, the substance has melted. Therefore, melting point is determined to be somewhere between 1040 and 1050 °C.

At 1040 °C no sign of melting was observed on removal from the furnace, whereas at 1050 °C, the substance has melted.
Description of key information
Results from thermogravimetric analysis showed that the test substance did not melt under the test conditions up to the limit of the test equipment (1,000 °C). No self-ignition was observed under the test conditions up to the limit of the test equipment (1,000 °C). No decomposition was observed under the test conditions up to the limit of the test equipment (1,000 °C). An additional study was conducted to determine the melting point of the test substance. An attempt was made to melt the substance in a furnace using temperatures of up to 1,050 °C. At 1,040 °C no sign of melting was observed on removal from the furnace, whereas at 1,050 °C, the substance has melted. Therefore, melting point is determined to be somewhere between 1,040 and 1,050 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 1 040 °C
