Pre-test:
No melting could be observed. Only the colour of the test item changed from white to beige.
Main study:
No melting point or range could be determined.
The detection limit of the test system is between -80 °C and 400 °C.
The melting point or range of this test item is much higher; the test item did not even melt in the flame of the gas burner.
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.
The test item did not melt under the conditions of the test, and was determined to be > 400 °C.
Description of key information
> 400 °C
Key value for chemical safety assessment
Additional information
Two studies are available, which examined the melting point of Lanthanum carbonate under GLP-conditions according to OECD 102 (Paulus 2009, Weissenfeld 2006).
The test item did not melt under the conditions of the tests, the melting point was determined to be > 400 °C.
