Purity: 99.9%.

Properties and Application of Coated aluminum nanoparticle:

1. The thermal properties of various uncoated and coated aluminum nanoparticle and their effects on the thermal stability, outgassing behavior, and electrostatic discharge sensitiveness of various energetic materials were studied.

2. The coated on aluminum nanoparticle had a layer of 7-25% mass of polymer.

3. Aluminum nanoparticles are very reactive in the presence of water, resulting in aging problems. The coating of polymer has a minor effect on the reactivity of aluminum nanoparticles with water.

4. The study shows that the coated aluminum nanoparticle is more stable than uncoated Nano powder in humid atmospheres.

5. Aluminum nanoparticle is commonly added to explosive and propellants to improve their performance.

Because it has large specific surface area, aluminum nanoparticle can produce dramatic improvements in the performance of some energetic materials.

6. The aluminum nanoparticle after long term storage in air under ambient conditions are found to be extremely active. A coating has been proposed as a solution to protect Al nanopowder from aging.
