EC number: 285-561-1 | CAS number: 85117-09-5 Mixtures of chemical substances produced by burning (below 1200°C) natural variants of limestone or chalk containing from 10 to 20%, or more, of clayey or siliceous materials which are predominantly SiO2, Al2O3 and iron oxide. Consist primarily of 2CaOsb.2, Ca(OH)2, CaO and 2CaOsb.2O3. 3CaO.2SiO2, 4CaOsb.2O3. Fe2O3, 2CaOsb.2O3sb.2, CaCO3 and SiO2 may also be included.

Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-03-05 to 2010-05-21
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 2009-11-26
- Type of method:
- thermal analysis
- Remarks:
- DSC
- Melting / freezing pt.:
- > 450 °C
- Remarks on result:
- other: Significant thermal events did not occur. The unchanged residue appearance (grey powder) on completion of each determination confirmed that no phase transition of the test material had occurred during the heating up to 450 °C.
- Conclusions:
- The melting/freezing point temperature of the test material has been determined to be greater than 450 °C (> 723 K).
