Description of key information

In a read across approach with diiron trioxide and triiron tetraoxide, the melting point of zinc ferrite is assessed.
The following melting points are listed:
Diiron trioxide 1565 °C
Triiron tetraoxide 1597 °C
Due to the structural similarity it is very likely the melting point of zinc ferrite is > 1000°C at 1013 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
1 000 °C

Additional information

Should read > 1000 °C.

There is no data available for zinc ferrite, read across with diiron trioxide and triiron tetroxide is proposed to cover this endpoint. These substances are members of the ”Iron Oxides Category”. In regard to structure, physico-chemical properties, environmental fate characteristics, ecotoxicity and toxicity, the grouping of diiron trioxide, triiron tetraoxide, iron hydroxide oxide, iron manganese trioxide, manganese ferrite, and zinc ferrite in the "Iron Oxides Category" is justified. Therefore, a read across between these substances to cover physico-chemical endpoints for zinc ferrite is justified.
