Description of key information

No key information is available on the boiling point of magnesium zirconium oxide. Data from the safety data sheet of a manufacturer showed the substance to have a boiling point of ca. 3800°C (Imerys, 2015). This data can be considered as supportive evidence. No tests need to be performed as the substance is a solid which melts above 300°C (Column 2, REACH Annex VII).

Key value for chemical safety assessment
