EC number: 939-967-7
CAS number: -
The melting point of the test material is 2344 °C.
1. Information on zirconium dioxide (CAS# 1314-23-4)Two peer-reviewed data from handbooks (2710 and 2680 °C)2. Information on erbium oxide (CAS# 12061-16-4)Peer-reviewed data from handbook (2344 °C).3. Conclusion on erbium zirconium oxideUsing a weight of evidence approach based on individual data for zirconium dioxide and erbium oxide it is expected that erbium zirconium oxide has a similarly high melting point.
1. Information on zirconium dioxide (CAS# 1314-23-4)
Although only two values are available it can be safely concluded that
the melting point of zirconium dioxide is approximately 2700 °C, making
it environmentally irrelevant. The difference between the reported
handbook results is assumed to be caused by the error of measurement at
high melting temperatures.
2. Information on erbium oxide (CAS# 12061-16-4)
A value for the melting point of the substance was obtained from a peer
reviewed handbook. The melting point of the substance is reported to be
3. Conclusion on erbium zirconium oxide
It is expected that the substance has a similarly high melting point as
the read across substances zirconium dioxide and erbium oxide. No exact
value can be derived, however, this is not necessary as the high melting
point is environmentally irrelevant.
