- Conclusions:
- The test item Cesium fluoroaluminate has no boiling point up to a temperature of 500 °C at atmospheric pressure (1008 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Reference
In the temperature range of 380 °C – 470 °C an endothermic effect (melting) was observed. No further thermic effects could be observed up to the maximum measured temperature of 500 °C.
Results of the DSC-measurements
| Sample weight [mg] | Onset of Effect [°C] | Range of effect [°C] | Weight loss [mg] | Atmospheric pressure [hPa] |
| 30.45 | 435.67 | 400 – 470 (endo) | 0.45 | 1007.5 |
| 18.74 | 434.06 | 380 – 470 (endo) | 0.11 | 1018.0 |
During the heating phase a distinct endothermic effect was observed in the temperature range of 380 – 470 °C, which can be assigned to the melting of the test item. Since no further endothermic effects could be observed up to the maximum test temperature of 500 °C, it can be stated that the test item has no boiling point up to 500 °C.
Description of key information
The test item Cesium fluoroaluminate has no boiling point up to a temperature of 500 °C at atmospheric pressure (1008 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Key value for chemical safety assessment
