- Executive summary:
The melting point of substance "reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" was measured in a study according to EU Methods A.1 (Melting / Freezing Temperature) and A.2 (Boiling Temperature) Regulation (EC) No. 440/2008. Differential scanning calorimetry (DSC) as thermal analysis method was used. According to ECHA REACH TGD R.7a, this method can be used to evaluate melting and boiling point in a single test. No departure from the base line of the heat flow record was observed that might indicate a melting, boiling or decomposition process while the substance was heated up to and including a temperature of 310°C (583 K).
Melting point > 310°C
Reference
Description of key information
> 583 K (310°C)
EU Methods A.1 (Melting / Freezing Temperature) and A.2 (Boiling Temperature) Regulation (EC) No. 440/2008. Differential scanning calorimetry (DSC) as thermal analysis method was used.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:

Additional information
The melting point of substance "reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" was measured in a study according to EU Methods A.1 (Melting / Freezing Temperature) and A.2 (Boiling Temperature) Regulation (EC) No. 440/2008. Differential scanning calorimetry (DSC) as thermal analysis method was used. According to ECHA Guidance R.7a, subchapter R.7.1.3.3 (2017), this method can be used to evaluate melting and boiling point in a single test.
No departure from the base line of the heat flow record was observed that might indicate a melting, boiling or decomposition process while the substance was heated up to and including a temperature of 310°C (583 K). Thus, melting point is > 583K (310°C).
To fill information on melting point into Chesar via IUCLID, the value of 310°C has been allocated as key value.
