Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Reason / purpose for cross-reference:
reference to same study
Qualifier:
no guideline followed
Principles of method if other than guideline:
The melting point of the pigment was estimated by consulting phase diagram that included the characteristic crystalline phase of the pigment and, as far as possible, had the same composition, through this latter point was not always feasible.
GLP compliance:
no
Type of method:
thermal analysis
Remarks:
Differental thermal analysis
Melting / freezing pt.:
> 1 000 °C

The DTA test identified no transition in the 100 -1000 °C range that might indicate pigment fusion, it therefore being inferred that the pigment melting point lies at higher temperatures than the maximum temperature in the range examined.

Conclusions:
The DTA test identified no transition in the 100 -1000 °C range that might indicate pigment fusion, it therefore being inferred that the pigment melting point lies at higher temperatures than the maximum temperature in the range examined.
