Description of key information

Divanadium pentaoxide starts melting at 681°C at atmospheric pressure.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
681 °C

Additional information

According to reliable handbook data (e.g. CRC handbook) the melting point of divanadium pentaoxide ranges from 681 -690°C at atmospheric pressure. The handbook data are considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance" and therefore, the melting temperature is regarded as reliable.
