Reference
Thermal Stability
The DSC-measurement (prepared at 1014 hPa) in a closed glass crucible with the test item showed no endothermic or exothermic effects up to a temperature of 500°C. An optical inspection showed no changes of the test item by the measurement.
Melting Point / Melting Range (DSC)
The measurements in aluminium crucibles (measured at 1014 hPa and 1012 hPa respectively) with a hole under nitrogen showed an endothermic effect in the temperature range of 90 – 235 °C. No further effect was observed up to a temperature of 600 °C.
An optical inspection showed no changes of the test item by the measurement.
Due to the optical inspection it can be concluded that the test item has no melting point at atmospheric condition up to the maximum temperature of the measurement (600 °C).
Due to the results of the capillary measurement the results from the DSC-measurement are confirmed. Therefore it can be assumed that the endothermic effect in the DSC-measurement has been caused by the evaporation of water from the test item.
Description of key information
Cobalt hydroxide oxide has no melting point up to 600 °C.
Key value for chemical safety assessment
