Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Dihydrogen hexafluorozirconate is an aqueous solution and its boiling point is thus somewhat above that of water (100 °C). The exact boiling-point elevation depends on the concentration of the acid, but is not considered practically relevant for the chemical safety assessment. Experimental confirmation of the boiling point is scientifically not justified (in accordance with REACH Annex XI, section 1) and a boiling point of 100°C is selected as the key value for chemical safety assessment.
