Results and discussion
Melting / freezing point
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: Charcoal showed no signs of melting under the test conditions described.
Any other information on results incl. tables
The determination was performed in duplicate. In both determinations, no melting was observed up to 404°C. In an additional experiment, the test item was set into a muffle oven and heated up to 1095 °C.
No melting of the test item of charcoal (Probe 2: C-Fix = 80.5%) was detected up to a temperature of 1095°C.
Under the experimental conditions used in the study (highest temperature: 1095°C), no melting point of the test item charcoal (Probe 2: C-Fix = 80.5%) could be determined.
Applicant's summary and conclusion
- Conclusions:
- Since there were no signs of melting up to a temperature of >1000°C, no melting point of the test item could be determined.
