Description of key information
During a preliminary screening on dilithium tetraborate, the test item melted to form small, spherical particles. No ignition or propagation was observed. Dilithium tetraborate can be considered as non-flammable.
Flammability is the ability of a substance to burn or ignite, causing fire or combustion. The degree of flammability depends largely upon the chemical composition of the material. The chemical composition of lithium metaborate is identical to dilithium tetraborate consisting of the same elements/functional groups. Any variations due to the range of trigonal and tetrahedral species between the substances are not expected to lead to any changes in the flammability potential of these substances. It can therefore be concluded that lithium metaborate is not flammable.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
A preliminary screening test on calcium metaborate was conducted which showed no ignition or propagation was observed. It was concluded that no further testing was required. Calcium metaborate was considered as non-flammable and therefore does not meet the criteria for physico-chemical classification. As the flammability result is not close to a classification boundary for the physico-chemical hazards, any variations due to the range of trigonal and tetrahedral species between the substances are not expected to lead to any changes in the classification and labelling of the category. It is therefore expected that all calcium borate substances listed in this category including calcium tetraborate will not meet the criteria for physico-chemical classification.
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.
