Results and discussion

Boiling point
Boiling pt.:
> 600 °C
Atm. press.:
>= 1 012 - <= 1 014 hPa
Remarks on result:
other: based on DSC-measurement, performed under nitrogen

Any other information on results incl. tables

The measurement in aluminium crucible (measured at 1014 hPa and 1012 hPa respectively) with a hole showed an endothermic effect in the temperature range 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 and the results from the melting point it can be concluded that the test item has no boiling point at atmospheric condition up to the maximum temperature of the measurement (600 °C).

Applicant's summary and conclusion

Conclusions:
The test item, cobalt hydroxide oxide, has no boiling point under atmospheric conditions up to 600°C.
