Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Column 2 of REACH Annex VII (standard information requirements for substances manufactured or imported in quantities of 1 tonne per year or more) of Regulation (EC) No 1907/2006, a study to determine the boiling point of a substance does not need to be conducted for solids which melt above 300°C.
The melting point (decomposes) of boron nitride is >2730°C (1)(2)(see section 4.2 of the IUCLID dossier).
Due to the inherent properties of boron nitride (solid with melting point >300°C), performance of a study to determine the boiling point is not required under Regulation (EC) No 1907/2006 (REACH).
