Additional information

In accordance with column 2 of REACH Annex VII, the boiling point study (as required in section 7.3) has not been completed as the substance was observed to decompose prior to boiling.

Decomposition occurs with evolution of ammonia and carbon dioxide. A gel-like substance remains which does not change state. This material has been analysed and found to be hydrated zirconium oxide.
