key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
not applicable
Remarks:
The guideline is not stated in the report, but the study follows principles of the OECD 102 guideline.

Key result
Melting / freezing pt.:
<= 937 °C
Atm. press.:
ca. 101 325 Pa
Decomposition:
no
Remarks:
No decomposition was observed.

The test sample melted by 937°C. No decomposition was observed.

Conclusions:
The test sample melted by 937°C. No decomposition was observed.
Executive summary:

The melting point of the test item was determined using differential thermal analysis. The guideline is not stated in the report, but the study follows principles of the OECD 102 guideline. This is a non-GLP experimental study and there are minor restrictions in reporting but it is otherwise acceptable as the key study for this endpoint.

Description of key information

Bismuth silicate melted by 937°C. No decomposition was observed.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
937 °C

Additional information

The melting point of the test item was determined using differential thermal analysis (Schefter 2016). The guideline is not stated in the report, but the study follows principles of the OECD 102 guideline. This is a non-GLP experimental study, however is considered acceptable as the key study for this endpoint.
