1,5-Diaminotetrazolecopper(I) nitrate (CDN) is a novel primary explosive. Its layered structure provides high impact sensitivity and detonation velocity, making it a safe and powerful candidate for explosives applications.
Area of Science:
- Materials Science
- Inorganic Chemistry
- Energetic Materials
Background:
- Primary explosives are crucial for initiating secondary explosives.
- Developing safer, high-performance primary explosives remains a key challenge in energetic materials research.
Purpose of the Study:
- To synthesize and characterize 1,5-Diaminotetrazolecopper(I) nitrate ([Cu(DAT)3]NO3, CDN).
- To evaluate the sensitivity, detonation properties, and structural characteristics of CDN for potential use as a primary explosive.
Main Methods:
- Single-crystal X-ray diffraction for structural confirmation.
- Impact and friction sensitivity tests.
- First-principles calculations to understand structural behavior under stress.
- Detonation velocity measurements.
Main Results:
- CDN exhibits a layered planar structure with weak π interactions.
- High impact sensitivity (1.5 J) and low friction sensitivity (84 N).
- Calculations show easy sliding and low resistance to deformation (Young modulus, 10.13 GPa).
- Experimental detonation velocity of 7600 m s⁻¹ was recorded.
Conclusions:
- CDN's unique structure contributes to its energetic properties.
- CDN is a promising high-performance primary explosive candidate.
- Its properties suggest it is safe to handle, sensitive for initiation, and powerful for detonating secondary explosives.
