Description of key information

According to peer reviewed handbook data, the melting point of zirconium oxide is 2710 °C.

According to peer reviewed handbook data, the melting point of yttrium oxide is 2439 °C.

According to peer reviewed handbook data, the melting point of erbium oxide is 2344 °C.

Key value for chemical safety assessment

Additional information

The melting points of the constituent oxides were considered together as part of a weight of evidence approach. This was used to inform on the likely melting point of the registered substance.

Following the weight of evidence approach the melting point of the registered substance is considered to be greater than 2000°C
