Melting point / freezing point
Administrative data
Link to relevant study record(s)
- 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:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- capillary method
- Specific details on test material used for the study:
- Batch number: 17/1791
Purity / Composition: 99% Barium Zirconate CAS 12009-21-1
Chemex reference: ECO 181004
Appearance (specified):Creamy/white powder - Key result
- Melting / freezing pt.:
- > 410 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- not determinable
- Remarks:
- substance showed no sign of melting or decomposition at the temperature of the test
- Conclusions:
- Barium Zirconate was tested several times over a temperature range of 200 to 410°C. Throughout the test the sample was observed closely, however there were no changes to the physical state of the sample. No melting occurred throughout all the replicates.
The Buchi Model No. B540 melting point apparatus is able to reach a maximum temperature of 410°C and therefore the three tests were carried out considering the highest temperature that could be recorded with this method.
The conclusion of this test is that Barium Zirconate has a melting point >410ºC based on the results obtained.

Description of key information
Barium Zirconate was tested several times over a temperature range of 200 to 410°C.
No changes to the physical state of the sample were observed. No melting occurred throughout all the replicates up to a maximum temperature of
410°C. The conclusion of this test is that Barium Zirconate has a melting point >410ºC based on the results obtained.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
