EC number: 231-131-3 | CAS number: 7440-22-4
Explosiveness
Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Description of key information
Silver metal is devoid of any chemical structures commonly associated with explosive or self-reactive properties, such as metal peroxides, peroxo-acid-anions, azides, and halogen oxides). Silver metal is not flammable, not auto-flammable, not flammable in contact with water and silver does not show pyrophoric properties. Silver is thermally stable (melting point ca. 960°C, boiling point ca. 2200°C). Further, it is noted that despite long-term industrial use of the substance, it is not classified for explosive properties according to UN transport regulations. Therefore, silver is not considered to be explosive (and experimental verification appears scientifically not justified).
