Conclusions:
According to the available handbook data, zinc selenite has a melting point of 621°C at atmospheric pressure.

Description of key information

According to CRC handbook (2008) the melting point of zinc selenite is 621 °C at atmospheric pressure.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
621 °C

Additional information

According to reliable handbook data (e.g. CRC handbook) the melting point of zinc selenite is 621 °C. Handbook data 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 value could be regarded as valid.
