Reference
Thermal stability:
The DSC-measurement in a closed glass crucible (measured at 1014 hPa) with the test item showed no endothermic or exothermic effect, respectively.
DSC:
The DSC-measurement in aluminium crucible with a hole with the test item showed no endothermic or exothermic effect, respectively.
An optical inspection showed no changes of the test item by the measurement.
Due to the measurement and 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).
Description of key information
No melting point can be stated. Lithium cobalt dioxide has no melting point under atmospheric conditions up to 600 °C.
Key value for chemical safety assessment
Additional information
The melting point of the test substance was determined according to OECD guideline 102 with the differential scanning calorimetry method (DSC). The test item was heated up from ambient to the final temperature (600 °C) at a constant heating rate (10 K/min) in a defined atmosphere (nitrogen). The quantity of heat absorbed or released was measured and recorded. Aluminium crucibles with a small hole were used as containers for the test item and as empty reference crucible.
The result of the measurement and the optical inspection showed that lithium cobalt dioxide has no melting point at atmospheric condition up to the maximum temperature of 600 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
