- ca. 1 100 °C
Any other information on results incl. tables
The authors stated, that the BET surface area droped dramatically to 1 m2/g because of the melting of the ZSM-5 zeolite at 1100 °C.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
