Description of key information

The melting point of cesium iodide was determined to be 628 °C at 1013.25 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
628 °C

Additional information

The determination of the melting temperature was performed according to EU test method A.1 and OECD Guideline 102 by applying the differential scanning calorimetry. The heat flow curves show one sharp endothermic peak with a peak maximum temperature at 631 °C / 631 °C and an extrapolated onset temperature of 627 °C / 628 °C indicating the melting temperature at ambient pressure. Therefore, the melting point of cesium iodide was determined to be 628 °C at 1013.25 hPa.
