Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 06-07-2009 to 10-08-2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- thermal analysis
- Melting / freezing pt.:
- > 723 K
- Remarks on result:
- other: ± 0.5
- Conclusions:
- The melting temperature of Sinter Ore was determined to be > 723 ± 0.5 K. No sign of any significant thermal event.
- Executive summary:
The meting point of the test material ws investigated according to the standardised guideline, EU Method A.1.
Under the conditions of the study, the melting point of the test material was determined to be > 723 ± 0.5 K. There was no sign of any significant thermal event.
Reference
As there were no significant thermal events, it was determined that no changes in the physical state of the test material occurred over the range of 25 to 450 °C.
During both determinations, an endotherm was displayed by both Thermograms. These are tabulated in table 3 (see below).

Description of key information
The melting point of manganese ores, reduced is > 723K (> 450 °C).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 450 K
Additional information
The meting point of the test material ws investigated according to the standardised guideline, EU Method A.1. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of the study, the melting point of the test material was determined to be > 723 ± 0.5 K. There was no sign of any significant thermal event.
The actual melting point of the substance is expected to be much higher than 1 000 °C and the temperature of 450 °C stated is the maximum temperature possible in the DSC apparatus.
